Bently Nevada 330103-00-06-10-02-05 Proximity Sensor

Reliable Non-Contact Displacement Measurement for Turbomachinery

The Bently Nevada 330103-00-06-10-02-05 proximity sensor provides precise shaft vibration and position readings without physical contact. This 5 mm sensor system features a tip diameter of 8.1 mm and a case diameter of 14.2 mm for secure mounting. Its total length reaches 80 mm, with a threaded portion of 21.6 mm and an unthreaded section of 30.5 mm. The device weighs approximately 90 grams and operates on a standard -24 Vdc negative power supply. Operators can rely on this sensor for continuous monitoring of journal bearings, thrust bearings, and gear mesh dynamics.

Measurement Precision and Thermal Performance

This proximity sensor delivers a linear range from 0.25 mm to 2.03 mm with a sensitivity of 7.87 mV/µm. It captures frequency responses from 0 to 10 kHz, covering both static gap voltages and dynamic vibration signals. The sensor tip withstands temperatures from -35°C to +177°C, while the extension cable remains functional up to +260°C. Such thermal tolerance ensures stable readings across steam turbines, gas compressors, and large motors. The included 6.0 meter cable features a polyurethane jacket that resists oil, hydraulic fluids, and mechanical abrasion.

Detailed Technical Specifications

System Components and Interface Options

This proximity sensor includes the probe body, a 6.0 meter extension cable, and two coaxial connectors for straightforward field wiring. An integral connector at the probe end provides a weatherproof seal against moisture and dust ingress. The terminal block at the driver side accepts standard 22 AWG wires for power and signal connections. The system stores negligible internal energy, which supports intrinsic safety certifications for hazardous area installations. Users can pair this sensor with the Bently Nevada 3300 XL Proximitor or the 3500 Monitoring System for complete signal conditioning.

Installation Procedures and Maintenance Tips

Installing this proximity sensor requires a 14 mm wrench and standard mounting brackets for the threaded case. The threaded body allows precise gap adjustments using the supplied locking nut mechanism. Regular visual inspections of the cable jacket and connector integrity will prevent signal degradation over time. This sensor excels in predictive maintenance programs where early detection of shaft movement prevents costly failures. For optimal accuracy, calibrate the system against AISI 4140 steel targets to match factory calibration curves. The robust construction and generous cable length provide installation flexibility for remote monitoring configurations.
