Checking Accelerometers Using Vibration Equipment

Friend Clintdsa,

The TK-3 is not designed to test the accelerometers, you can use it to test axial and radial probes (proximity sensors), the wobbulator is used for simulate radial vibration in order to check the input signal to the monitors showing radial vibration and also can be used to check the keyphaser.

You can also with the TK-3 create the calibration curve to the proximity probe+extention cable+proximitor.

In order to check the accelerometers, I can recommend this equipment: Portable Vibration Calibration System Model 9100C (The Modal Shop, Inc), I received this suggestion from the Bently Nevada technicians.

Hope this helps

It has been simply ages since I messed with accelerometers--we got our graphs by pen and ink on a moving paper. If your acceleration is in the ballpark of 1 or 2 g, you should be able to turn it upside down (or is it downside up?), and it will indicate a 2g change in the acceleration.
