Frequently Asked Questions (FAQ)

Q1: What sensing principle does this probe use?
A1: It employs eddy-current induction to convert shaft gap into an AC voltage signal.

Q2: Can the cable length be customized?
A2: Yes, variants are available in 2 m, 3 m, 6 m, and longer upon request.

Q3: How is the probe connected?
A3: Via a standard 10-pin MIL-C-26482 stainless-steel connector to the 3300 XL monitor card.

Q4: What is the optimal sensing gap?
A4: Recommended gap is 0.25–1.0 mm for best linearity and sensitivity.

Q5: Does it need periodic calibration?
A5: Calibration is typically set at installation; re-calibration intervals depend on usage and operating conditions.

Q6: How does it handle electromagnetic interference?
A6: Shielded PTFE cable and grounding spring assembly provide robust EMI protection.

Q7: What environmental standards does it meet?
A7: Rated –40 °C to +120 °C, 100 g shock, and complies with IEC EMC requirements.

Q8: Can it tolerate occasional contact with the shaft?
A8: It can withstand light rubs at low speed but should not be forced into heavy contact.

Q9: How is linearity specified?
A9: Linearity is better than 1 % of full scale within the recommended gap range.

Q10: Where can I obtain technical documentation?
A10: Full datasheets and installation guides are available through Bently Nevada’s official support channels.
