Frequently Asked Questions (FAQ)

Q1: What is the sensing principle of this probe?
A1: It uses eddy-current induction to convert shaft proximity into a proportional AC voltage signal.

Q2: Can I customize the cable length?
A2: Yes, cable lengths ranging from 0.1 m up to 12 m are available to suit your installation needs.

Q3: How does the probe connect to the monitor card?
A3: It connects via a 10-pin MIL-C-26482 stainless-steel connector directly into a 3300 XL probe input.

Q4: What is the optimal gap setting?
A4: A gap of 0.25–1.0 mm provides the best 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 EMI?
A6: The shielded PTFE cable and grounding spring assembly ensure excellent EMI immunity.

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

Q8: Can it withstand mechanical shocks?
A8: Yes, it is rated for 100 g half-sine shocks of 11 ms duration.

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

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