Frequently Asked Questions (FAQ)

Q1: What sensing principle does this probe use?
A1: Eddy-current induction converts shaft proximity into a proportional AC voltage signal.

Q2: Can I order a different cable length?
A2: Yes, variants are available in 0.1 m, 1.5 m, 2 m, 3 m, 6 m, and custom lengths.

Q3: How is the probe mechanically mounted?
A3: It uses an integrated spring assembly that maintains consistent air-gap and allows slight axial movement.

Q4: What is the optimal sensing gap?
A4: 0.25–1.0 mm provides the best balance of linearity and sensitivity.

Q5: Does this probe require external power?
A5: No, it is powered and conditioned by the 3300 XL monitor electronics.

Q6: How resistant is it to electromagnetic interference?
A6: The PTFE-insulated, shielded cable and grounding spring deliver robust EMI immunity.

Q7: What temperature extremes can it handle?
A7: Rated for continuous operation from –40 °C to +120 °C.

Q8: Can it withstand mechanical shocks and vibrations?
A8: Yes, it’s rated for shocks up to 100 g (11 ms half-sine) and industrial vibration levels.

Q9: How often should it be calibrated?
A9: Factory-calibrated; recommended field recalibration intervals depend on operating hours and environmental stress.

Q10: Where can I access detailed installation guides?
A10: Full datasheets, installation manuals, and calibration certificates are available through Bently Nevada’s support portal.
