PCB signal conditioner electric noise

Highlighted

Hi!

 

I am using the piezoelectric pressure transducers with NI card along with PCB ( 482A16) signal conditioners for pressure measurement. The signal conditioners are showing up noise peak at 50 Hz frequency and above. Is this because of the cross talk between the channels or something else? I ensured that the grounding of the whole measurement set up is proper. 

 

Please guide for the problem.

 

With regards,

Ganesh

Do a measurement without a sensor: Replace the ICP sensor(s) (I assume you have a ICP sensor) with  a resistor R=10V/<supplycurrent>  directly at the amplifier input.

If you still have the noise it is probably the powersupply of the amplifier. BTDT

“ground” is a convenient fantasy
