Bently Nevada 330101-01-13-05-01-00 3300 XL 8 mm Proximity Transducer

Precision Displacement Measurement for Rotating Machinery

The Bently Nevada 330101-01-13-05-01-00 functions as a complete 8 mm proximity transducer system for shaft monitoring applications. This integrated unit combines a probe, extension cable, and proximitor in a single assembly for straightforward installation. Its tip diameter measures 8.1 mm, while the case diameter reaches 14.2 mm to ensure secure mounting in standard probe holders. The overall length extends to 80 mm, featuring a threaded portion of 21.6 mm and an unthreaded section of 30.5 mm. This transducer weighs approximately 150 grams, including all connected components.

Electrical Performance and Environmental Tolerance

This system operates on a -24 Vdc negative power supply and delivers a sensitivity of 7.87 mV/µm across its linear range of 0.25 mm to 2.03 mm. It responds to frequencies from 0 to 10 kHz, capturing both static gap voltages and dynamic vibration signatures. The probe tip withstands temperatures from -35°C to +177°C, while the extension cable remains functional up to +260°C. Such wide thermal tolerance makes this transducer suitable for steam turbines and centrifugal compressors. The included 5.0 meter cable features a polyurethane jacket that resists oil, water, and abrasion.

Detailed Technical Specifications

System Components and Interface Details

This transducer system incorporates the probe body, an integral 5.0 meter extension cable, and a built-in proximitor module. The proximitor housing includes a terminal block for connecting power and signal wires directly. A single coaxial connector at the probe end provides a weatherproof seal against moisture ingress. The system stores negligible internal energy, which supports intrinsic safety ratings for hazardous locations. Operators can interface this transducer with the Bently Nevada 3500 Monitoring System or standalone diagnostic instruments.

Installation and Maintenance Considerations

Installing this proximity transducer requires a 14 mm wrench and suitable mounting brackets for the probe. The threaded case permits precise gap adjustments using the locking nut provided with the unit. Regular visual inspections of the cable jacket and connector integrity prevent signal degradation. This transducer excels in predictive maintenance strategies where early fault detection reduces operational risks. For best results, calibrate the system against AISI 4140 steel targets to maintain factory accuracy. The integrated design eliminates separate cable connections, simplifying field wiring and reducing potential failure points.
