FAQ

Q1: Can this probe be directly connected to monitoring systems without a proximitor?

A1: No, the probe must be connected to a 3300 NSv Proximitor sensor to condition the signal before transmitting to monitoring systems.

Q2: What is the typical linear measurement range of this probe?

A2: The 3300 NSv probe provides a linear range of approximately 1.0 mm (40 mils) depending on shaft material.

Q3: How does shaft material affect probe calibration?

A3: The probe is factory calibrated for AISI 4140 steel. Other shaft materials require material correction factors for accurate readings.

Q4: Can the probe operate in high-vibration environments?

A4: Yes, it is specifically designed to withstand mechanical vibration and provide stable readings.

Q5: Is the probe sensitive to electromagnetic interference?

A5: The coaxial cable and sensor design provide strong EMI shielding, minimizing interference.

Q6: How does temperature affect measurement accuracy?

A6: Within the specified operating range, the probe compensates for thermal variations and maintains accuracy.

Q7: Can the probe be used in hazardous areas?

A7: Yes, when used with approved proximitor and installation practices, it can meet hazardous area certifications.

Q8: What is the frequency response limit of this probe?

A8: It supports a frequency response from DC up to approximately 10 kHz.

Q9: How should the probe gap be adjusted during installation?

A9: The initial gap should be set within the proximitor’s linear range, typically 1.0 mm, using feeler gauges or calibration tools.

Q10: Can the probe be extended with additional cable length?

A10: Cable length must match the proximitor’s design length; custom factory-matched probe and cable assemblies are required.
