A micro-electromechanical spring-mass-system is continuously measuring the acceleration and transforms the measured data into an analog 4-20mA output signal. The sensor complies with the standards of DIN EN 50155 for railway vehicles. It is espacially intended to be used in the on-board network of rail vehicles.
Its extrem rugged housing enables applications in harsh conditions in the outskirt area of the vehicle, directly at the bogie. The sensor impresses by its high ruggedness against impact, dust as well as moisture and guarantees high reliability. The device detects accelerations in a measuring range of ± 4g and operates with 110 Volt supply voltage.
