Acceleration Sensors

DIS-1-03

Acceleration sensors

(QG series)

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.

Acceleration sensor

Functions of Accelerometers

Measurement of acceleration and vibration, active vibration damping, transport monitoring

Applications

Agricultural machinery, wind mills, containers

Acceleration Sensor Housing

Many of the DIS sensors in the QG range use a unique universal plastic housing concept, known as QUADRO®. The advantage is the very compact size, simple installation and the fact that the electronics are fully sealed which provides a high degree of ingress protection (IP67).
