Product Description

Overview

The Bently Nevada 330180-91-00 is a precision 3300 XL Proximitor Sensor designed for high-accuracy machinery vibration and position monitoring. As part of the 3300 XL 8mm proximity system, it converts displacement into analog signals to provide real-time gap measurement between the probe tip and a conductive target. Built for extreme industrial environments, it delivers reliable performance in rotating machinery, compressors, turbines, and pumps.

Technical Specifications

Functional Highlights

• Full Interchangeability: Works seamlessly with all 3300 XL probes and extension cables without bench recalibration.

• Legacy Compatibility: Backward-compatible with 3300-series 5mm and 8mm sensors, allowing incremental system upgrades.

• High-Density Installation: DIN-rail mount ensures space-saving installation with electrical isolation.

• API 670 Compliant: Meets standards for linearity, temperature stability, and mechanical configuration.

• Robust Terminals: Spring-loaded screwless terminals provide reliable connections resistant to vibration.

• Precision Monitoring: Maintains measurement accuracy with strict total system electrical length compliance.

Usage Notes

The combined electrical length of the probe, extension cable, and sensor must total exactly 9.0 meters. Deviations from this length can produce measurement errors and non-linear output.

Applications

• Rotating machinery vibration monitoring in turbines, compressors, and generators

• Bearing clearance measurement and predictive maintenance systems

• High-speed shafts and fluid-film bearings in power generation

• Retrofit projects upgrading legacy 3300 systems to XL series
