Product Overview

The Bently Nevada 330850-50-00 is a 3300 XL series 25 mm proximity front sensor designed for high-precision vibration and position monitoring in industrial machinery. It is part of the Bently Nevada 3300 XL monitoring system, widely used for critical asset protection and condition monitoring.

This sensor is engineered to measure shaft displacement and vibration in rotating equipment such as turbines, compressors, pumps, and motors. It provides highly accurate and stable signals, making it essential for predictive maintenance and machinery protection systems.

Technical Specifications

Function and Working Principle

The 330850-50-00 sensor operates using eddy current proximity technology, where a high-frequency electromagnetic field is generated at the probe tip. When the sensor is placed near a conductive target (such as a rotating shaft), eddy currents are induced on the surface.

The system measures changes in the electromagnetic field to determine:

• Shaft vibration amplitude
• Radial displacement
• Axial movement
• Machine dynamic behavior

This non-contact measurement method ensures high accuracy and eliminates mechanical wear, making it ideal for continuous monitoring of high-speed rotating machinery.
