Bently Nevada 330103-20-25-05-02-CN 3300 XL 

Proximity Probe

Configured for fluid-film bearing vibration and position tracking in machinery monitoring systems, the Bently Nevada 330103-20-25-05-02-CN (330103 Proximity Probe) provides direct physical/electrical execution. It operates as an element of the 3300 XL 8 mm Proximity Transducer System, generating a voltage output proportional to the gap between the probe tip and the target.

Hardware Specifications

Proximity Transducer Mechanical Monitoring Attributes

The 3300 XL 8 mm system requires strict gap voltage validation to maintain standard eddy-current probe scaling. Operating installations utilize a benchmark of -10 VDC targets near the midpoint of the linear range to secure structural voltage-to-gap calibration. Correct orientation prevents cross-talk suppression failures when positioning multiple proximity probes in close physical proximity around rotor dynamics observation vectors.

Frequently Asked Questions

Q: Does this proximity probe require matched bench calibration with the specific extension cable and Proximitor?

A: No. All 3300 XL 8 mm components support complete interchangeability across standard system lengths, eliminating individual matching protocols.

Q: How is cross-talk prevented when installing multiple probes on the same machine surface?

A: Maintain the minimum specified physical clearance between probe tips to eliminate mutual electromagnetic interference and preserve standard transducer scaling.

Field Installation Guidelines

Ensure the unthreaded and threaded portion configurations exactly clear internal hardware obstructions during insertion. Thread the unit into the brackets until reaching the specific gap voltage value (typically verified via voltmeter at the Proximitor output). Secure the probe locknut utilizing standard industrial torque values to avoid damage to the casing threads. Route the integral coaxial cable using protective conduit, ensuring the shield terminates at the target monitoring rack ground node.
