Minsk Research Institute of Radiomaterials of the National Academy of Sciences of Belarus offers consumers strain sensors DD under a manufacturing agreement and is looking for partners interested in distribution services agreement.

OJSC "Minsk Research Institute of Radiomaterials" of the National Academy of Sciences of Belarus manufactures strain sensors DD designed to monitor the amount of deformation (compression) of the car axle under load and provide information via CAN interface. The sensors are made as a tensoresistive bridge that perceives the deformation of the sensor base.

Strain sensors DD are used as part of a car overload protection system, and to register weight parameters in urban municipal equipment.

The sensor is attached to car axle using four (4) M8x1 bolts to the slats with threaded holes.

The principle of operation of the sensor is based on measuring the relative elongation or compression of an element due to a change in the load applied to it.

The sensor is characterized by:
* the presence of a built-in measuring module that performs the functions of amplifying the output signal from the strain gauge bridge;
* the presence of a 24-bit analog-to-digital converter;
* the presence of a 32-bit microcontroller that calculates the load value in kilograms using constants stored in the microcontroller's memory when the user performs the sensor calibration procedure;
* correction of the load calculation result taking into account the influence of ambient temperature using the built-in temperature sensor;
* output of the load and temperature measurement result in error-protected digital format (CAN 2.0 B);
* small overall and installation dimensions;
* low sensitivity to external mechanical factors during operation;
* high reliability and the necessary margin for pressing the working surfaces of the sensors to the object, which eliminates the violation of sensor calibration associated with the effect of "slippage" when exposed to extreme loads.
