Frequently Asked Questions (FAQ)

Can this probe directly replace my old probe?

Yes, if the old probe is a Bently Nevada 3300 XL 11mm model with the same electrical and mechanical specs. Always check the full part number suffix for cable length and connector type.

Can I cut or extend the probe cable?

We strongly advise against it. Cutting or splicing changes the cable’s electrical characteristics. This affects signal quality, impedance, and system calibration. Always order the correct cable length.

The operating range is -51°C to +177°C. Why is installation above -34°C recommended?

The internal Viton O-ring seal becomes brittle at very low temperatures. Installing (tightening) below -34°C can crush or cut the seal, causing it to fail. The probe can operate at the lower temperature after proper installation.

How can I check if the probe is working correctly?

The best method is using a dedicated probe tester to check gap voltage and linearity. A simple ohmmeter can check DC resistance (should be ~8.5 ohms), but this is not a full functional test.

Based on experience, what is the most common cause of probe failure?

Cable damage is most frequent. During installation, cables can be pinched, sharply bent, or pulled at the connector. This breaks internal wires. Always secure the cable properly using cable glands or clamps.
