Measuring strain gage signal using Picoscope 3424

Post by rakhmad » Fri Mar 15, 2019 2:51 am

Currently, we are trying to capture the signal from the strain gage on the Hopkinson bar apparatus using Picoscope 3424. We are using a simple Wheatstone bridge that powered by a 9 volt battery as an excitation voltage, however, until now, the results are not as expected, could anyone provide any suggestion?

The form of the strain gage and the results can be seen in the attachment file.

Hi

Are you able to post a psdata file with the captured data so I can have a closer inspection?
(If you can't post it on here you can send it into support@picotech.com)
Do you have an example or sketch of what you're expecting the waveforms to be like?
