accelerometer static test
(OP)
hi guys,
i want to verify the operational characteristics of an accelerometer without using a shaker table can one test the integrity of a vib accelerometer by inputing a pulsed waveform and analysing the response signal? any info welcome.

For dynamic testing of the sensor - you need to shake, shake, shake...

I use this as a quick check for the entire instrumentation chain when doing a modal analysis.
Probably not quite what the original poster had in mind!

Presumably, the idea is that the voltage pulse stresses the crystal, and upon release of the input, the crystal relaxes and generates essentially a transient response equivalent to the effect of a step function shock input.
This is a quick & dirty check, but there's no means of verifying that the transfer characteristic of the housing and mounting haven't been perturbed.
