Product Overview

The Bently Nevada 330101-00-20-10-02-05 is an 8 mm eddy-current proximity probe used to measure shaft displacement without contact. Installed at bearings or thrust locations, it produces a displacement signal that is processed by a compatible Proximitor sensor and monitoring platform to support machinery protection and condition monitoring.

This probe is selected when stable vibration and position measurements are required in rotating equipment environments. When used as part of a complete 3300 XL transducer system (probe, extension cable, and Proximitor), it supports reliable trending of radial vibration and axial position to help identify developing faults before they lead to forced outages.

Hardware Parameters

Additional technical notes

• The probe is not powered as a standalone device; excitation and signal conditioning are provided by the Proximitor sensor.

• Total system calibration depends on matching probe type, extension cable length (if used), and Proximitor model.

• The mention of a “3500 rack receiving the signal” is system-level; the probe itself is compatible with appropriate Bently Nevada proximity systems when matched correctly.

Operational Use Cases

Typical installation scenarios include:

• Steam and gas turbines for continuous bearing vibration and thrust position supervision (application dependent)

• Centrifugal compressors where shaft motion trending supports protection logic and reliability programs

• Critical process pumps and motor-driven trains where early vibration changes indicate bearing wear or hydraulic instability

• Power generation and oil & gas rotating assets where temperature variation and lubricant exposure demand stable transducer performance

Installation considerations

• Set and verify probe gap per site procedures to avoid saturation and maintain linear response

• Maintain cable routing practices that reduce EMI pickup, especially near VFDs and high-current conductors

• Confirm steady transducer “OK” status after installation to validate the probe/cable/sensor signal path
