CM_Sensor_BAM-myBridge

We developed the »μ-bridge« sensor to capture sound waves and flexural vibrations in machines and plants (e.g. on components, solid bodies, etc.). The structure-borne sound waves emitted by machine parts are characteristic for the wear status of a part. 

For the µ-bridge sensor the force of the sound wave is converted to a measurement voltage without a detour through a spring mass damper system. This even makes it possible to detect structure-borne sound waves and flexural vibrations at frequencies from 10 kHz to under 1 Hz with high resolution and bandwidth; this means that the sensor is particularly well suited for measurements on slowly rotating or vibrating parts.
