Bently Nevada 330703 XL 11 mm | Non-Contact Vibration Probe

Product Description – Bently Nevada 330703-000-070-10-02-00 Proximity Probe

Description / Overview

The Bently Nevada 330703-000-070-10-02-00 Proximity Probe is a rugged eddy-current displacement sensor designed for precision measurement in demanding industrial environments. It accurately measures the distance between the probe tip and a conductive surface, typically a rotating shaft, for both radial vibration and axial thrust position monitoring. Moreover, it generates Keyphasor® signals to provide reliable phase reference and shaft speed data. This probe forms a key component of the 3300 XL 11 mm Transducer System, which delivers non-contacting vibration and displacement measurements with a longer linear range compared to the standard 8 mm system.

In addition, the probe integrates seamlessly with extension cables and Proximitor® sensors, ensuring high accuracy and signal integrity for machinery protection systems on turbines, compressors, motors, and pumps. The robust stainless-steel housing and wide operating temperature range guarantee durability under harsh industrial conditions.

FAQ

Q1: Is this probe compatible with existing 3500 monitoring systems?
Yes, but software updates may be required to list the 3300 XL 11 mm system as compatible.

Q2: Can this probe measure both vibration and axial thrust?
Yes, it is designed for radial vibration, axial thrust, and Keyphasor® signal generation.

Q3: What is the maximum operating temperature?
The probe operates reliably between –51 °C and +177 °C for most industrial applications.

Q4: Does the 11 mm tip offer advantages over the 8 mm probe?
Yes, the larger tip provides a longer linear range for extended displacement measurement.

Q5: Can it replace the older 7200-series probes?
Yes, but all 3300 XL 11 mm components must replace the older 7200-series parts for proper system operation.
