FAQ
Q1: What type of output does this probe provide?
A1: The probe provides an AC voltage output that is proportional to the distance between the probe tip and the target.
Q2: Can this probe measure non-ferromagnetic materials?
A2: No, the 3300 NSv probes are optimized for ferromagnetic targets only.
Q3: What is the recommended cable length for accurate measurements?
A3: Standard factory configuration comes with a 0.5 m cable. For longer runs, use Bently Nevada approved extension cables.
Q4: What is the operating temperature range of this probe?
A4: The probe operates reliably between -40°C and 120°C.
Q5: How is the probe calibrated?
A5: Calibration is performed at the factory and the probe comes with a preset gap. No field calibration is required for typical applications.
Q6: Can this probe be used in explosive environments?
A6: Only if paired with certified intrinsic safety barriers or housings according to industry standards.
Q7: What is the typical frequency response of the probe?
A7: The probe supports a frequency range of 0–10 kHz.
Q8: Is the probe compatible with the standard 3300 XL monitoring system?
A8: Yes, it is fully compatible with 3300 XL and other 3300 series monitoring systems.
Q9: How should the probe be installed relative to the target shaft?
A9: The probe tip should be aligned with the shaft surface according to the preset gap specified by Bently Nevada.
Q10: Can the probe detect rotor rubs or shaft eccentricities?
A10: Yes, the probe detects displacement and vibration signals that can indicate rubbing or shaft eccentricity when analyzed with appropriate monitoring equipment.
