Description

The Bently Nevada 144181-50 is a 3300 XL 5/8 mm Proximitor Sensor designed for continuous non-contact vibration and position monitoring in critical industrial rotating machinery. As an integral component of Bently Nevada Machinery Monitoring Systems, this eddy current proximity sensor measures dynamic shaft vibration, axial position, and keyphasor reference signals on medium to heavy industrial assets.

The sensor processes signals from 3300 XL proximity probe assemblies, converting mechanical displacement into a highly accurate, proportional electrical voltage output. With an optimized scale factor of 7.87 V/mm, the Bently Nevada 144181-50 Proximitor Sensor delivers exceptional signal linearity and stability across varying operating environments. Its rugged solid-state design ensures long-term reliability in harsh plant conditions, directly supporting predictive maintenance programs and automated machinery protection circuits.

Features

• Eddy current proximity sensing technology for precise non-contact shaft vibration and displacement measurements.
• Calibrated voltage output characteristic with a precise target scale factor of 7.87 V/mm.
• Solid-state industrial enclosure designed for mounting in field junction boxes or monitoring racks.
• High linearity and low temperature drift for reliable signal delivery to monitoring systems.
• Seamless integration with Bently Nevada machinery protection platforms and TSI monitoring loops.

Applications

• Machinery Protection Systems (TSI / Vibration Monitoring)
• Radial shaft vibration measurement on heavy rotating machinery
• Axial (thrust) position measurement on turbines, compressors, and pumps
• Keyphasor speed and phase reference timing signal measurement
• Predictive maintenance data acquisition for critical industrial assets

Installation Guidelines

1. Verify that the Bently Nevada 144181-50 model matches system design requirements and sensor probe compatibility.
2. Inspect the sensor body and connectors for physical integrity before mounting.
3. Securely mount the Proximitor Sensor inside a grounded, weatherproof field enclosure or system cabinet to protect against environmental contamination.
4. Route extension cables and probe leads away from high-voltage electrical lines or heavy magnetic interference sources.
5. Ensure proper shielding and signal grounding connections to maintain signal clarity and prevent noise induction.
6. Verify electrical power supply and output signal wiring prior to energizing the monitoring system.
