BAM53–Reliable and precise acceleration measurement with up to three measuring axes : NORIS Group GmbH

MEMS sensor, type approved according to railway standard DIN EN 50155
High accuracy due to very low noise
Wide frequency range
Measurement of up to two axes (triaxial on request)
Ideal for predictive maintenance
Robust and compact design, customer-specific connections possible

Due to the compact stainless steel design the acceleration sensor type BAM53 is very robust. It can be easily adapted to customer requirements: Dimensions and electrical connection are variable. The BAM53 can be fitted with a cable protection for applications in extreme conditions on request. Furthermore, the sensor is type approved and so, can be used for wheel set bearing- and bogie monitoring and for derailment detection.

The sensor’s proven capacitive MEMS principle enables monitoring at a lower frequency and has good temperature stability as well as good repeat accuracy. With the uniaxial, biaxial or triaxial variant on request, up to three measuring axes are available even for demanding applications.
