The sensors can be used in measuring the radiation temperature without any contact. For different radiation temperature ranges various filters are available. The sensor type SMTIR9902 contains a temperature sensor for measuring the temperature of the sensor itself. The temperature range of the sensor-element is between -40 to 100 °C. The sensor is available in a standard TO-05 encapsulation and is standard wise equipped with a 5.5 micrometer filter. For a small field of view there is an infrared sensor available with a silicon lens.
The UTI provides interfacing for all kind of resistive and capacitive sensors.
For convenience design-in there is an evaluation board available. In combination with the free downloadable software the application will work in shortest time.
In general the screened resistors are also sensitive to temperature which means a compensation for temperature effects is required. For the Smartec pressure sensors this compensation is done in the amplifier to obtain a stable analogue output.
In the delivery program a lot of outputs circuits are available like bridge, analogue, digital and I2C output. In case your requirements are not in the list of data sheets, please, contact your nearest dealer. In general we have the possibility to full fill your needs concerning pressure range and output.
By means of a commercial Raspberry Pi board and some Smartec SMT172 sensors a very accurate data acquisition system can be built with an accuracy of better than 0.1 C. The temperatures can be readout via your
LAN system which is available on the internet. The software example below is, as ever, can be downloaded for free and of course can be changed by the user.
A Humidity measurement system using the Smartec SMT172 temperature sensor by means of a psychrometric process
Smartec has designed a low cost, accurate Wet-Bulb temperature measurement system, which you
can easily build yourself for approximately Euro 100,-, using Smartec temperature sensors, our I2C
solution and a microcontroller board such as an Arduino or Raspberry pie. In this article we will show
you how to do that. We have developed, built and extensively tested two different versions of this
system and we are sharing this information with who ever wants to use it.
