FAQ

Q1: What is the typical operating voltage for this proximity probe?

A1: The probe operates using standard 3300 XL system excitation voltage, typically 24 VDC.

Q2: Can this probe measure at distances smaller than 25 mm?

A2: Yes, the probe provides linear measurement down to zero proximity, though the specified range is optimized up to 25 mm.

Q3: Is the probe compatible with other Bently Nevada monitoring systems outside the 3300 XL series?

A3: It is primarily designed for 3300 XL systems; use with other systems may require signal conditioning or calibration adjustments.

Q4: How does temperature affect the probe’s performance?

A4: Performance remains stable within the operating temperature range of -40°C to 120°C; extreme temperatures may require additional protective measures.

Q5: What type of output signal does this probe provide?

A5: It outputs an AC differential voltage proportional to the shaft displacement.

Q6: Can the cable be extended beyond 9 m without affecting signal quality?

A6: Cable extensions may be possible with shielded and matched impedance wiring, but the maximum recommended length should not exceed the system specifications to avoid signal degradation.

Q7: Does the probe require calibration before installation?

A7: The probe is factory-calibrated, but verification with a reference standard during installation is recommended.

Q8: Is the probe resistant to EMI (Electromagnetic Interference)?

A8: Yes, the shielded twisted pair cable design minimizes EMI influence, ensuring stable readings.

Q9: Can the probe operate in high-vibration environments?

A9: Yes, the 3300 XL probe is designed to withstand high vibration without measurement drift or damage.

Q10: What maintenance is required for long-term operation?

A10: Minimal maintenance is needed; periodic inspection of the connector, cable integrity, and signal quality is sufficient.
