3D MEMS

The 3D MEMS Acceleration Sensor is a high sensitivity/low noise triaxial acceleration sensor, which can provide simultaneous measurements of acceleration in 3 mutually perpendicular axes.

Micro Electronic Mechanical Systems (MEMS) acceleration sensors provide a compact and effective method for making static and dynamic measurements of acceleration. The MEMS technology uses the capacitance between plates to measure acceleration. Mass at the end of a plate is affected by acceleration, thus deflecting the plate and changing the capacitance of the device. This capacitance is converted to produce a current output proportional to acceleration. 

Bachmann offers this sensor to provide a 3D measurement of acceleration. The output is via a standard 5 pin M12 connector, giving retrofit compatibility with the Bachmann Monitoring 2D MEMS Acceleration Sensor.

Uses of the Bachmann Monitoring 3D MEMS Acceleration Sensor are in the field of structural motion measurement. The output can be used for blade unbalance assessment (mass and aerodynamic), structural health monitoring and tower natural frequency assessment.

Mounting is done by means of M4 screws – either on existing threaded holes or on a corresponding adapter plate, which can be fixed e.g., by means of mounting magnets - (see accessories).
