Over the course of 30 years, DIS Sensors has built up a reputation in the field of high quality sensor technology. We develop, produce and sell sensors for various applications from our headquarters in Soest, the Netherlands. We value innovation and know-how above all else. The result: high-quality products and solutions from DIS Sensors to serve the global market.
We offer a wide range of sensors for measuring inclination and acceleration as well as rotary encoders. DIS Sensors has an excellent reputation in the field of customised solutions and we are proud to be your partner in innovation. Because we work with a network of carefully selected suppliers, we can also produce wide ranges at highly competitive prices.
The QG series of inclination sensors measures angles in 1 or 2 axes. These products are based on robust MEMS technology, in which capacitance differences can be converted into an analogue voltage within a micro-mechanical sensor chip. This analogue voltage is proportional to the angle to which the sensor is exposed. The modular design makes it easy to adapt the sensors to specific requirements.
An inclination sensor is used in situations where accurate positioning or constant monitoring of the angle in relation to gravitational pull is essential. An inclination sensor measures the angle with respect to a horizontal position, whereby an imaginary line from the centre of the earth serves as a reference.
An inclination sensor has a very wide range of applications since it can be mounted anywhere and offers flexibility in mechanical design. The sensor output has two components: a static (slope) component and a dynamic (acceleration) component. The sensor output is always a combination of these two components. The inclination sensors from DIS have a standard bandwidth of 10 Hz, although it is possible to reduce this bandwidth further at the clients request.
The QG series of acceleration sensors measure acceleration in 1, 2 or 3 axes. These products are based on robust MEMS technology, in which capacitance differences can be converted into an analogue voltage within a micro-mechanical sensor chip. This analogue voltage is proportional to the acceleration to which the sensor is exposed. The modular design makes it easy to adapt the sensors to specific requirements. The housing is available in metal (aluminium and stainless steel), as well as in plastic. DIS acceleration sensors have a higher bandwidth than inclination sensors so they can measure faster movements with very high accuracy.
A tilt switch is a type of switch that switches at a certain angle as compared to the horizon (similar to the old mercury switch). It is in fact an inclinometer with a switching output. Since gravity serves as a reference maximum mounting freedom is achieved.
The tilt switches from DIS Sensors are based on MEMS technology and intelligent microcontroller algorithms. As a result, single or twin axis switches can be implemented with any desired switching angle. The output can be NPN or PNP. A SIL1 / PLc tilt switch for safety applications completes the portfolio. An optional configurator is available to configure the switch (angles, delay times, filtering).
DIS tilt switches are available with the following general specifications:
The QR series of rotary encoders enable contact-free measurement of an angular displacement from 0° to 360° without a mechanical stop. Two types of housing are available. The QR30 housing, where the sensor and magnet are mounted separately from each other, and the QR40 housing, where the magnet is integrated into the rotating shaft in the housing.
In the QR30 range, the sensor and magnet are mounted separately from each other, where the customer can mount the supplied magnet on its rotating axle (on-axis). The maximum distance of 3 mm between the magnet and the sensor provides sufficient space for mechanical tolerances under extreme conditions. Various outputs are available with a 10 or 12-bit resolution for a wide range of applications. While the back of the QR30 sensors is being sensitive, the QR30N sensors have got a sensitive nose.
The QR30 series is available as absolute or incremental rotary encoders. An absolute rotary encoder contains an analog output which is linear with the angle of rotation, up to 360°. After switching on the power the sensor knows directly in which position it is located. An incremental encoder is specially suitable for rotational velocity of a shaft. The output of the sensor consists of pulses (A and B). The number of pulses per revolution can be between 32 and 1024. On the basis of the phase shift between the A and B signal can be determined if the shaft rotates clockwise or counterclockwise.
In contrast to the QR30 series, in the QR40 series of rotary encoders the magnet is built into the sensor. The standard shaft is D-shaped. The QR40 also has a zero-input, which makes it possible to zero the device after installation, ensuring a non-critical mounting procedure.
An inclination sensor measures the angle with respect to a horizontal position, with an imaginary line from the centre of the earth serving as a reference. It can be mounted anywhere and offers great flexibility in mechanical design. This combination makes DIS Sensors inclinometers an excellent choice for tilt monitoring of, for example, fork/ scissor lifts and aerial work platforms.
Concrete pumps contain long boom extensions which often have to reach over long distances or (high) obstacles. The primary concern of working safely with concrete pumps is to situate the truck correctly. The inclination sensors of DIS Sensors can be used to continuously monitor the exact position of the boom to guarantee stability.
DIS Sensors acceleration sensors can measure fast movements which makes them perfect to monitor maximum vibrations of wind turbines and to prevent damage. For safety applications DIS can provide redundant versions.
DIS Sensors inclination sensors perfectly meet the requirements of the medical industry to measure accurately the angular position of, for example, MRI or CT scanners and mobile operation chairs.
Blowout preventer (BOP) systems play an important role by monitoring the pressure and flow of oil and gas in offshore drilling which make them essential within this application. For accurate levelling of these BOP systems we recommend DIS Sensors inclinometers.
To make sure elevator doors can be controlled throughout the complete open-closed cycle you can use the absolute and incremental encoders of DIS Sensors. With an absolute rotary encoder it becomes possible to control the door speed to be slowed in time and also detect if there are obstructions along the cycle. Absolute encoders give an analog output which is linear with the angle of rotation, up to 360°. After switching on the power the sensor knows directly in which position it is located.
