filtering pressure transducer noise

[Engineering Intern]

I am working on a system that displays force readings versus time for numerous hydraulic presses but I am having a problem with noise.  Attached is a screen shot of the noise I am getting.  Any suggestions on what kind of filtering I should start with would be greatly appreciated because I have no idea.  Thanks!

It depends on what you want to do with the results.

Your limits seem to imply a range of -50 kN to +150 kN and the noise seems to be about 0.5 kN peak to peak. Thus, the noise is about 0.0025 times the full scale span. This does not seem to be out of line for a load cell or pressure transducer. If you set the graph with Autoscale Y = Off and the Scale Min and Max equal to the values in the Limits cluster, it will not look like much noise.
