    Campbell Scientific -
    when measurements matter.


     
Product Portfolio
  • Dataloggers & Data Acquisition Systems

  • Campbell Scientific dataloggers are at the center of our rugged, reliable data acquisition systems. Our dataloggers share similar measurement and programming capabilities; selection of the appropriate datalogger depends mainly on the type, number, precision, and speed of measurements required.
    • CR200X-Series Dataloggers
       

    • CR200X-series dataloggers (our smallest, lowest-cost dataloggers) have an input channel configuration and small size that make them optimal for measuring one or two simple sensors. Some of the models have onboard spread-spectrum radios, allowing them to be used as wireless sensors.
    • CR800-Series Measurement and Control Dataloggers

    • The CR800 and CR850 dataloggers provide precision measurement capabilities in a rugged, battery-operated package. The two models differ in their keyboard display. The CR800 uses an external keyboard display, the CR1000KD, which connects to the CR800 via its CS I/O port. The CR850 includes an on-board keyboard display as part of its integrated package.
    • CR1000 Measurement and Control System

    • Following in the tradition of the CR10 and CR10X, our CR1000 dataloggers measure more sensors than our CR200X- and CR800-series dataloggers. The CR1000 is a compact, modular line of dataloggers with a measurement and control module, external power supply, and keyboard display. Their power consumption and packaging are optimized for unattended network applications.
    • CR3000 Micrologger®
       

    • Campbell Scientific's CR3000 Micrologger® is a self-contained, rugged datalogger that includes battery-backed, real-time clock and nonvolatile data storage. It has an on-board keyboard and 128 x 64 backlit LCD for accessing information on-site. The CR3000 features removable Input/Output connections, a CS I/O port, peripheral port, and RS-232 port.
    • CR5000 Measurement and Control System

    • This rugged, high performance, integrated data acquisition system has a built-in keyboard, graphics display, and PCMCIA card slot. It combines 16-bit resolution with a maximum throughput of 5000 measurements per second. The CR5000 is available with a built-in sealed rechargeable battery base or in a low profile version without batteries.
    • CR9000X-Series Measurement and Control Systems

    • The CR9000(X)-series dataloggers are ideal for applications that require rapid measurements. Measurements at rates up to 100,000 samples per second can be made with 16-bit resolution. The user inserts up to nine I/O modules to configure the system for a specific application. A smaller version, the CR9000XC, accepts up to five I/O modules.
    • CR7 Measurement and Control System

    • Primarily used in multi-parameter research and industrial applications, this large modular datalogger allows the user to customize the measurement system to their specific needs. Any combination of I/O Cards can occupy slots in the I/O Module. The CR7 provides high resolution (up to 50 nV) and a large number of channels. It is our only datalogger that can do thermocouple psychrometry.
  • Measurement & Control Peripherals

  • This family of peripherals expands the already formidable measurement and control capabilities of Campbell dataloggers. Measurement peripherals are situated between the datalogger and its sensors, while control peripherals are situated between the datalogger and external device(s) under datalogger control. Examples of measurement peripherals include vibrating wire interfaces, serial data interfaces, terminal input modules, and in most cases, multiplexers. Examples of control peripherals include relay drivers, some SDM peripherals, and occasionally, multiplexers. Some SDM devices can perform both measurement and control functions simultaneously.
    • Multiplexers

    • Multiplexers allow our dataloggers to measure more sensors. The number of analog inputs is increased by sequentially multiplexing sensor leads into "common" leads. The individual common leads are connected to datalogger analog inputs, excitation channels, or ground as required by the sensor. The datalogger controls the multiplexer using two control ports or one control port and one excitation channel.
    • Synchronous Devices for Measurement

    • Synchronous Devices for Measurement (SDMs) are a group of addressable peripherals that expand the datalogger's output and measurement capabilities. The datalogger controls the SDM output device by storing a value in a memory location, which is then used by the SDM to set a voltage or relay. Measurement devices store data from sensors which are regularly read into the datalogger through a control port.
    • Vibrating Wire Interfaces

    • These interfaces allow our dataloggers to read vibrating wire sensors. Vibrating wire (or vibrating strip) transducers are commonly used to measure strain, load, pressure, and water level. These sensors output a frequency signal generated by a vibrating filament that can be read on an analog channel.
    • Wireless Sensor Interfaces

    • These components are used to interface with our wireless sensors. Products included in this category are base stations, the wireless configurable sensor interfaces, and the CWS Sensor to PC Interface.
    • Relay Drivers

    • Relays are devices that can provide power directly to external devices that have modest power requirements, such as the small fans used in our Bowen ratio systems. Alternatively, these relay drivers can provide control signals to heavy-duty external relays that in turn can control power to heavy-duty, high-power equipment such as ventilation fans, aquacultural aerators, refrigeration units, or other electrically powered machinery.
    • Terminal Input Modules

    • These small modules are provide completion resistors for resistive bridge measurements, voltage dividers, and precision current shunts. They attach directly to the datalogger's input terminals. Each input module provides circuitry to connect one sensor, except for the voltage dividers, which can connect up to two single-ended sensors.
    • Miscellaneous Measurement and Control Peripherals

    • Measurement and Control Peripherals that don't quite fit into our other categories are included here.
  • Sensors

  • Our sensors are generally designed for long-term installation under adverse environmental conditions. Most of the sensors listed on our web site measure environmental and water resources parameters, but our dataloggers are not limited to measuring environmental sensors. Sensors used in industrial applications such as strain gages, accelerometers, hydraulic pressure transducers, are also available, either through our applications engineers or from a third party.

    Our dataloggers have many channel types and programmable inputs, enabling them to measure most commercially available sensors. Sensors that output voltage, pulse, SDI-12, RS-232, or 4-20 mA signals can be read using the datalogger's analog (single-ended and differential), pulse counter, SDI-12, RS-232, continuous analog output, digital I/O, anti-aliasing filter, and switched excitation channels.
    • Air Temperature Sensors

    • Campbell Scientific offers thermistors, thermocouples, and RTDs for measuring air temperature. The datalogger's programmability allows a variety of measurement options and output in units of the user's choice (e.g., °C , °F, °K). Naturally aspirated and fan-aspirated solar radiation shields are available for specific sensor models.
    • Air Temperature & Relative Humidity

    • Air temperature and relative humidity probes typically consist of two separate sensors packaged in the same housing. Often relative humidity is measured with a capacitive RH sensor, while air temperature is measured by a PRT. The HMP155A, HMP45C or CS215 is recommended in humid areas or applications in which accurate measurements of RH (especially above the 90% RH level) are important.
    • Barometric Pressure Sensors

    • Barometric pressure sensors measure fluctuations in the pressure exerted by the atmosphere. The sensors require protection from condensing humidity, precipitation, and water ingress and are typically housed with the datalogger inside an environmental enclosure. If the enclosure is airtight, the sensor's pressure port must be vented to the atmosphere.
    • Basic Weather
       

    • These sensors measure wind speed and direction, precipitation, barometric pressure, temperature, and relative humidity—all in a single device that has no moving parts.
    • Conductivity Sensors
       

    • Conductivity sensors measure how well a solution conducts a current. The more ions that are in the solution, the higher the conductivity
    • Digital Camera
       

    • If you believe a picture is worth a thousand words, our digital camera is just what you need! Designed to work in harsh environments with very little power, our digital camera can take a picture on demand (driven by datalogger programming) or on a timed basis.
    • Dissolved Oxygen Sensors

    • Dissolved oxygen is a critical parameter in determining the health of aquatic systems. In many aquacultural applications, measurement of decreased oxygen levels is used as the primary indicator to start up aerators.
    • Distance Sensors
       

    • The most common applications are measuring snow depths and water levels. Ultrasonic sensors determine the distance to a target by sending out ultrasonic pulses and listening for the returning echoes that are reflected from the target. The time from transmissions to return of an echo is the basis for obtaining the distance measurement.
    • Duff Moisture Sensors
       

    • Duff is an important component of forest fire fuel. An accurate knowledge of moisture content in duff material is critical to those conducting scheduled burns as well as those attempting to battle out-of-control fires.
    • Electrical Current Sensors

    • Electrical current sensors detect the flow of current along an electrical wire by measuring (or sensing) the magnetic field that is set up by the flow of electrical current. As such, the sensors are external to the jacket of the ac power cable and there is no direct electrical connection between the sensor and ac power.
    • Electric Field Sensors
       

    • Like electrical charges repel and unlike charges attract. An electric force field, referred to as an electric field, is said to exist around electrical charges. Electric field defines the force per charge (E = F/q), and has both a magnitude and direction (vector quantity). The units of electric field are Newtons/Coulomb, which is equivalent to the more commonly expressed units of Volts/meter (V/m).
    • Evaporation
       

    • Evaporation gages determine the evaporation rate by measuring the changing water level in an evaporation pan. They consists of a float, pulley, and counterweight attached to a potentiometer mounted through a gear assembly in a weatherproof housing. The potentiometer produces
      a resistance output proportional to the position of the float
    • Freezing-Rain and Ice Detectors

    • Freezing rain sensors detect the presence of icing conditions so that appropriate actions can be taken to prevent damage to power and communication lines, to warn of road hazards, or to keep ice off of a plane's wings.
    • Fuel Moisture and Fuel Temperature

    • Campbell Scientific offers sensors that emulate and measure the moisture content and temperature of similarly-sized twigs on the forest floor. These 10-hour fuel moisture and fuel temperature sensors are often incorporated in our pre-configured or custom fire-weather stations. When connected to a datalogger with telemetry capability, the user can automatically monitor changing fuel conditions without having to visit the measurement site.
    • GPS Global Positioning Sensors

    • These sensors use Global Positioning Satellites (GPS) to determine position. There are three segments in determining position: satellites, ground stations, and sensors. The sensors access the satellites that circle the earth (there are 24).
    • Heat, Vapor, and CO2 Flux

    • By finding the covariance between the vertical wind speed fluctuations with temperature against humidity and carbon dioxide fluctuations, the sensible and latent heat flux, as well as vapor and CO2 fluxes, can be found. Virtual sensible heat flux can be determined by finding the covariance between the sonically determined temperature and vertical wind speed fluctuations.
    • Infrared Gas Anaylzers
       

    • Campbell Scientific offers both closed-path and open-path infrared gas analyzers that produce high-quality measurements in the field. The closed-path analyzer simultaneously measures absolute carbon dioxide and water vapor densities, sample cell temperature, and pressure. The open-path analyzer simultaneously measures absolute carbon dioxide and water vapor densities, air temperature, and barometric pressure.
    • Leaf Wetness Sensors
       

    • There are three leaf-wetness sensors classifications:

      1. Surface contact types that measure the electrical resistance of a water film on the leaf surface,
      2. Mechanical types that detect a change in sensor length or weight, or
      3. Electrical resistance types that are applied to mock leaves and are designed to emulate periods of leaf wetness after rainfall, dew, or spray.
    • ORP Sensors
       

    • Our ORP sensors measure the Oxygen-Reduction Potential of a solution. Used in tandem with a pH sensor, the ORP measurement provides insight into the level of oxidation/reduction reactions occurring in the solution.
    • pH Sensors
       

    • Our pH sensors measure of the acidity or alkalinity of a solution. The greater the hydrogen ion concentration, the smaller the pH; when the pH is above 7, the solution is basic (alkaline), and when it is below 7, the solution is acidic.
    • Precipitation Sensors
       

    • Campbell Scientific offers several types of precipitation measuring devices: tipping bucket rain gage, siphoning tipping bucket rain gage, heated rain gage, and a snowfall adapter.

      Sensor selection can be determined by precipitation type (rain or snow), orifice diameter, measurement range, and accuracy.
    • Present Weather
       

    • Present Weather Sensors are often a component of road, marine, and airport automated weather stations. They use a laser-based system to determine visibility, measure precipitation rate, and identify precipitation types (e.g., drizzle, rain, snow, and hail). This information is especially useful for assessing traveling conditions.
    • Road Weather and Surface Conditions

    • Campbell Scientific has sensors and measurement systems that provide data to monitor the atmospheric conditions near roadways as well as the conditions on the actual surface of the road.
    • Roadbed Water Content
       

    • Products for evaluating the volumetric and gravimetric water content of roadbed material both at the construction site and in the soil-test lab.
    • Snow Water Equivalency and Snow Depth

    • This section contains sensors that measure the amount of water contained within a snowpack or the depth of the snowpack.
    • Soil Heat Flux Sensors
       

    • Heat flux sensors measure the rate of energy transferred through a given surface. The sensors can be several thermocouples whose measurements are averaged, a thermopile, or a thermopile with a film heater.
    • Soil Temperature Sensors

    • Thermistors, thermocouples, thermocouple wire, and averaging thermocouples are standard soil temperature sensors that are available. Campbell Scientific dataloggers are capable of measuring most commercially available soil temperature sensors. The datalogger's programmability allows a variety of measurement options and output in units of the user's choice (e.g., °C , °F, °K).
    • Soil Volumetric Water Content

    • Soil water content indicates how much water is present in the soil. It can be used to estimate the amount of stored water in a profile or how much irrigation is required to reach a desired amount of water. Soil volumetric water content sensors provide a tool to measure the water content using hand-held sensors, or installing the water content sensors into the soil for long-term measurements.
    • Soil Volumetric Water Content Profiles

    • These probes monitor soil water content profiles. They can measure soil moisture at multiple depths and are easy to install. The output type can be specified; specifications vary based on output.
    • Soil Water Potential Sensors

    • Soil water potential sensors determine the energy status of water in soil. The energy state describes the force that holds the water in the soil. We offer sensors to measure soil water potential by two methods: the heat dissipation method or the electrical resistance method.
    • Solar Radiation Sensors
       

    • Campbell Scientific offers pyranometers, net radiometers, and quantum sensors, all designed to measure various aspects of the energy imparted by the sun on the Earth's surface.
    • Strain Gages
       

    • Strain gages are used to quantify live loads by measuring induced strains on various types of structures and components.
    • Surface Temperature Sensors

    • We offer two different technologies to measure surface temperature. Infrared temperature sensors are a non-contact means of measuring the surface temperature of an object or surface by sensing the infrared radiation given off by the subject. Other temperature sensors attach directly to the surface and measure temperature by physical contact.
    • Turbidity Sensors
       

    • Turbidity sensors measure suspended solids in water, typically by measuring the amount of light transmitted through the water. They are used in river and stream gaging, wastewater and effluent measurement, control instrumentation for settling ponds, sediment transport research, and laboratory measurements.
    • Water Level, Stage, & Flow Sensors

    • Water level, stage, or flow can be measured with many types of sensors: pressure transducers, bubblers, shaft encoders, or ultrasonic sensors. The location where you are measuring water level, the accuracy required, and the ease of installation all contribute to determining the best water-level sensor for your measurement site.
    • Water Samplers
       

    • Campbell Scientific offers both portable and stationary automatic water samplers for storm water, waste water, or other water-quality applications. These samplers use external vacuum pumps to draw water through intake tubing, instead of the traditional peristaltic pumps that induce flow by squeezing flexible tubing.
    • Water Temperature Sensors

    • Our thermistors are versatile, rugged temperature sensors optimized for long-term deployment. They can monitor water temperature for depths up to 50 feet. The thermistor circuit is measured by a datalogger excitation channel in tandem with a single-ended analog input channel.
    • Wind Speed and Wind Direction

    • Campbell Scientific offers a selection of quality wind sensors. Our wind vanes and anemometers are used in research, air quality, and general purpose meteorological applications. Anemometer only versions of some wind sensors are available for customers who wish to measure wind speed or wind run only.
    • Wireless Sensors
       

    • The CWS family of wireless sensors expands measurement possibilities by allowing sensors to be installed at a distance from the datalogger without cables. We offer an interface that connects to a variety of sensors, providing them with wireless capability. We also offer a wireless infrared radiometer and soil water content sensor.
  • Communications

  • Campbell Scientific offers a full range of communication devices. On-site peripherals include external data storage devices, PDAs, laptop or desktop computers, and displays.

    Telemetry peripherals support communications between the datalogger and one or more computers. These peripherals allow the user to access remotely the datalogger's real-time data, stored data, and programming. Examples include short haul, multidrop, telephone, radio, and satellite modems.

    Combinations of on-site and telemetry devices can be used in the same application for maximum flexibility, convenience, and reliability.

    • Software Development Kits, or SDKs, are available for software developers who wish to add custom capabilities or interfaces to our datalogger support software.
  • Power Supplies

  • Campbell Scientific's data acquisition systems are powered by reliable, inexpensive 12 Vdc sources. Power consumption by our dataloggers, peripherals, and sensors is minimal, allowing extended operation from our standard sealed rechargeable battery or set of alkaline cells. Systems that require more power can be supplemented with external rechargeable batteries, regulators, and charging sources (ac power or solar panels).
      • Alkaline Battery Packs

      • Contemporary dataloggers that can be powered by alkaline batteries include our CR800, CR850, CR1000, and CR3000. Some retired dataloggers, such as the CR500, CR510, CR10, CR10X, 21X, and CR23X, can also be powered by alkaline batteries.
      • Rechargeable Power Supplies

      • All of our dataloggers can be powered by a rechargeable power supply that consists of a rechargeable battery, regulator, and charging source. The charging source powers the system while float-charging the batteries. The batteries then provide back-up power if the charging source is interrupted.
  • Enclosures

  • Campbell Scientific enclosures are designed specifically for data acquistion applications. They protect equipment from dust, water, sunlight, or pollutants. Their white color reflects solar radiation, which reduces thermal gradients within the enclosure, a potential source of error in thermocouple measurements.
    • Standard Enclosures

    • Our standard enclosures are intended to accommodate a datalogger, power supply, and at least one peripheral. We typically refer to these enclosures by their internal dimensions (in inches). Please note that our larger dataloggers, the CR7, CR9000X, and CR9000, have their own enclosure options.
    • Prewired Enclosures

    • No time to wire your Campbell Scientific system? Let us do it for you. Campbell Scientific’s pre-wired enclosures combine flexibility with ease of use. You still have the flexibility to choose your system components, but installation is easy because the sensors are simply attached to pre-wired connectors on the outside of the enclosure. Campbell Scientific will even create a custom datalogger program for a small fee.
    • Installed Enclosure Accessories

    • This section includes a list of enclosure accessories that must be ordered at the same time as the enclosure.
    • Other Enclosure Accessories

    • These products are for securely mounting your equipment to the enclosure backplate, controlling the relative humidity inside of the enclosure, and providing adequate strain relief for sensor cables. All of this helps keep your equipment from becoming damaged by environmental and some man-made conditions. You can attach the enclosures to any of our tripods or towers, or to a user-supplied pipe.
  • Tripods, Towers, and Mounts

  • Our tripods and towers are sturdy instrument mounts designed to support sensors, wiring, antennas, and instrument enclosures. Both tripods and towers can be guyed (required for the twenty and thirty foot towers, recommended for tripods or ten foot towers subjected to severe winds). Tripods have adjustable legs that are deployed more easily in various soil/rock substrates. Towers allow higher measurement heights (to 30 ft), and the unguyed 10 ft model has a smaller footprint than a tripod. Campbell Scientific also offers several mounts for attaching sensors and antennas to the tripod or tower.
    • Instrumentation Tripods

    • For meteorological applications, the tripods can be augmented with mounts allowing attachment of sensors such as wind sets, pyranometers, and temperature/relative humidity probes. Barometers, soil temperature and moisture probes, and rain gages can also be used with tripod-based weather stations.
    • Instrumentation Towers

    • Our instrumentation towers are constructed of rust-free aluminum with a steel base. They consist of 10-ft sections that ease shipping and on-site installation.

      The towers allow higher measurement heights (to 30 ft) than the tripods, and the unguyed 10-ft model has a smaller footprint than our tripods.
    • Mounting Poles
       

    • Campbell Scientific offers several models of vertical poles for mounting sensors, enclosures, or other instrumentation. The models differ in length. Our 10-m model consists of five 6-ft galvanized-steel pipes and a stainless-steel base. The other models are constructed from stainless-steel, 1.5-inch IPS pipes.
    • Crossarms and Crossarm Brackets

    • Crossarms provide a rugged attachment point for securing meteorological sensors, antennas, and other peripherals to our tripods and towers. The design of all the crossarms places the sensor at a few feet away from the midline of the tower or tripod thereby serving to reduce the effects of the mount on the sensor measurement.
    • Mounts

    • Campbell Scientific sells several mounts for fastening sensors to an instrumentation tripod, tower, or pole. We also offer radiation shields and leveling platforms to help you obtain the most accurate measurements possible.
