Two-axis tilt angle sensors with enhanced shock compensation

Paul Boughton

Sensor specialist FSG has developed a tilt angle sensor based on MEMS technology (micro-electromechanical measuring systems) that monitors the inclination of construction machinery in rugged environments.

The PE-MEMS.../GS66 sensor series is equipped with an additional gyroscope to compensate linear accelerations and mechanical shock, making them suited for measuring tilt angles on, for example, ship platforms, working platforms or oil rigs.

The high-precision, redundant devices gauge x-axis and y-axis angles in a measuring range of ±30°. They achieve accuracies between ±0.08° and ±0.2° for angle ranges between 5° and 15°. Their passivated aluminium housings ensure IP67 ingress protection.

The sensors tolerate temperatures between -40 and +70°C and meet all technical safety requirements according to the IEC 61508 (SIL 2) and EN 13849 (PLd) standards. A CAN bus interface can be used with the CANopen or CANopen safety protocol for signal output.
