Connection Diagram

of the BC 201 Capacitive Acceleration Meters

Electric circuit of the BC 201 acceleration meter is shown on the figure below.
The electric scheme of the accelerometer of the BC
Acceleration meters BC 201 are connected to the AD converter, DA converter ZET 220 directly, while to the ZET 210, through the  ZET 410 or the  ZET 412 amplifier.Connection scheme via ADC accelerometer BC

The BC 201 acceleration meters can be connected to the  ZET 017 FFT Spectrum Analyzers through A 03-50 adapter; miniXLR5 socket is installed on the sensor cable to facilitate connection.
Connecting BC 201 to spectrum analyzers

The BC 201 acceleration meters are capacitive acceleration meters and can be used as linear acceleration and position sensors since they measure not only the variable component of the acceleration signal, but the direct component as well.

When the acceleration meter is installed on a sloped surface, it allows to measure the radial acceleration.
