Frequently Asked Questions (FAQ)
What is the best gap to set for this probe?
Set the gap to 1.27 mm (50 mils). This gives a -9 Vdc output. It is the sweet spot for radial vibration measurement.
Can this probe handle high temperatures?
Yes. The standard probe works from -52°C to +177°C. For higher heat up to 218°C at the tip, ask about the Extended Temperature Range model.
How does the FluidLoc cable help?
It prevents fluid ingress. Oil or process liquid cannot travel inside the cable. This stops leaks from the machine casing. It improves safety and cleanliness.
What is the main advantage of the 8mm design?
It is much stronger. The thicker body and encapsulation protect the coil. It survives better in harsh environments with physical contact risk.
From experience, what causes probe failure?
Most failures come from mechanical damage. Avoid hitting the tip during installation. Also, do not expose the seal to below -34°C regularly. This can crack the seal over time.
Is calibration needed after installation?
No. The probe has built-in interchangeability. The system scale factor is very stable. You can replace a probe without recalibrating the entire system in most cases.
