Accuracy of Thermocouple Tubes Without Calibration
Accuracy of Thermocouple Tubes Without Calibration Unexpected sensor failures, breakage and contamination happens to all of us. Hopefully you have a spare on hand when a sensor breaks in the field. You quickly switch out your vacuum tubes and proceed without hesitation. Unfortunately it’s rarely that easy – there are small electrical differences between each sensor; thus, your backup sensors will produce different readings on different vacuum gauges without calibration. Unfortunately, factory recalibration isn’t always an option at the time. This should raise some logical questions with technicians; how reliable and accurate are the readings produced by backup vacuum tubes? We set out
