Proximity Probe Calibration and Testing

Calibrating and Validating Proximity Probes with Portable Vibration Calibrator

9100-ppa01 proximity probe calibration kit product 3Non-contact proximity probes – or eddy current probes – are used to monitor vibration on the world’s most critical rotating equipment such as turbines and compressors. These transducers are reliable and accurate but are more complex to install correctly than other vibration instrumentation. Incorrect impedance leads to false alarms or catastrophic failures. Gap voltage alone is incapable of detecting such faults. Portable Vibration Calibrators identify incorrect probe sensitivity which leads to improper alarm operation. Calibrators test proximity probes dynamically, mechanically simulating the shaft motion that the probes will measure while in use. Pass your audit by quickly and easily creating probe calibration reports via a calibrator’s memory as opposed to manually charting voltage output vs. gap.
