FAQ

Q1: How does the 3300 NSv probe differ from standard 3300 XL probes?

A1: The NSv probe is designed for applications with limited space and has a smaller tip diameter, while the XL series is intended for general-purpose installations.

Q2: Can this probe be directly connected to monitoring equipment without a proximitor?

A2: No, it must be connected to a matched proximitor sensor to ensure proper signal conditioning and linear response.

Q3: What is the effect of cable length on calibration accuracy?

A3: The probe and extension cable must be matched to the proximitor as a system; mismatched lengths can lead to incorrect calibration.

Q4: Is the probe suitable for high-temperature machinery applications?

A4: Yes, it can operate reliably up to +180 °C, making it suitable for most industrial machines.

Q5: How does the probe handle electromagnetic interference (EMI)?

A5: The design includes shielding and proper grounding practices to minimize EMI effects.

Q6: What type of signal output does the proximitor provide when used with this probe?

A6: It provides a voltage signal proportional to the shaft displacement, typically 200 mV/mil.

Q7: Can the probe be used for axial thrust measurement?

A7: Yes, it is commonly applied for both radial vibration and axial position monitoring.

Q8: What happens if the probe gap is set incorrectly during installation?

A8: Incorrect gap setting can reduce linearity, affect sensitivity, and lead to false vibration readings.

Q9: Is this probe interchangeable with older Bently Nevada proximity probes?

A9: Only within the same NSv family and when matched correctly with its proximitor and extension cable.

Q10: How is temperature variation compensated in the probe system?

A10: The probe and proximitor are designed to compensate for thermal expansion and maintain linear accuracy across the operating temperature range.
