Bently Nevada 330903-00-21-10-02-05 11 mm Proximity Probe

Product Description

The Bently Nevada 330903‑00‑21‑10‑02‑05 is a precision 11 mm proximity probe engineered for non-contact measurement of shaft vibration and position in critical rotating machinery. It integrates seamlessly into the 3300 XL Proximity Transducer System, providing reliable output signals for both static and dynamic monitoring.

This probe is ideal for turbines, compressors, motors, and pumps where accurate displacement measurement is required under harsh operating conditions. Its robust stainless steel construction and proven eddy-current technology ensure long-term stability and performance.

System Components

• 3300 XL Proximity Probe (this model)

• 3300 XL Extension Cable (2.1 m cable length defined by “21”)

• 3300 XL Proximitor® Sensor

The system produces a voltage output proportional to the gap between the probe tip and the target conductive surface, enabling precise monitoring of shaft position, vibration, and Keyphasor® reference signals.

Key Features

• 11 mm probe tip diameter for larger shaft and bearing applications

• Non-contact eddy-current measurement for high-accuracy displacement sensing

• Supports dynamic vibration monitoring and Keyphasor® signal generation

• High linearity and measurement precision across the operating range

• Rugged stainless steel housing suitable for extreme industrial environments

• Fully compatible with Bently Nevada 3500 Series machinery protection systems
