The sensors are based one an advanced "bulk micro machined" MEMS technology. The three dimensional structure (3D MEMS) of these sensors comprise a pendulum made of mono crystalline silicon. The pendulum is hermetically enclosed between two silicon discs. From this construction results a long term stable, high resolution und shock resistant sensor.
A gas damping prevents overshooting and interfering resonance oscillation. The movement of the pendulum is measured capacitive by an ASIC. The sensors are mounted in a small, solid brass housing with fixing wholes. The output signal has a large span of 0,5 to 4,5 VDC over the measuring range. The power supply requirements are 5VDC or 7 -- 35 VDC.
