Current clamp for low temperature environment

Current clamp for low temperature environment

Current clamp for low temperature environment

I am searching for a current measurement clamp that can be used in a cold chamber at -30°C. The one we currently have can only be used to 0°C. Any suggestions? It needs to connect to a data acquisition unit; I'm not looking for a hand held meter. Thanks!

Wrong forum I think.
Do you need DC measurement?

RE: Current clamp for low temperature environment

I'd think you could just re-calibrate any decent clamp for the temperature range of interest; i.e. put the clamp in test chamber along with a wire loop, said wire loop passing out to ambient temperature current source that is calibrated or has a calibrated current sensor wired in series. Use the data taken to adjust measurements with the clamp in test, and (to be really complete) re-calibrate (verify calibration) after the test.

This is most likely a limitation of the electronics packaging.

How do you feel about insulating it and adding a heater or just reaching in with the meter from time to time and keeping it warm that way?
