floor vibration measurment

(OP)
hi,
i intend to measure floor vibration at a heavy machinery facility using fft spectrum analyser + sensor .
1)is it recomended to measure displacement or velocity or acceleration  at low frequencies (0-50 Hz).
2)is there a specific source for floor vibration measurments subject.

thanks,

RE: floor vibration measurment

Displacement would be best, but it is difficult to measure displacement of a floor beacuse of the problem of finding a static reference!

There are accelerometers available which measure down to DC

I recommend using a Bruel & Kjaer 2635 signal conditioner with a charge mode accelerometer.

The 2635 conditioner is capable of integrating the analog acceleration signal to velocity and double integrating to displacement.

I have some papers and software that I will send you on floor measurements if you send me an Email request.
