Bently Nevada 330101-00-16-10-02-05 3300 XL 8 mm Proximity Probe

Precision Vibration Monitoring for Critical Rotating Assets

The Bently Nevada 330101-00-16-10-02-05 belongs to the proven 3300 XL series and delivers accurate shaft relative vibration measurements for turbomachinery protection. This 8 mm probe system features a tip diameter of 8.1 mm and a case diameter of 14.2 mm for stable mechanical mounting. Its overall length reaches 80 mm, with a threaded section of 21.6 mm and an unthreaded portion of 30.5 mm. The device weighs approximately 90 grams and operates on a standard -24 Vdc negative power supply. This sensor provides continuous displacement data for steam turbines, centrifugal compressors, and large induction motors.

Electrical Characteristics and Environmental Durability

This proximity probe 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 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 ensures dependable operation across diverse process conditions. The included 16.0 meter cable features a polyurethane jacket that resists oils, hydraulic fluids, and mechanical wear.

Detailed Technical Specifications

System Components and Connection Details

This proximity probe package includes the probe body, a 16.0 meter extension cable, and two coaxial connectors for simplified field wiring. An integral connector at the probe end provides a sealed interface that prevents moisture and dust ingress. The terminal block at the driver side accepts standard 22 AWG wires for power and signal transmission. The system stores negligible internal energy, making it suitable for intrinsically safe installations in hazardous zones. Users can integrate this probe with the Bently Nevada 3300 XL Proximitor or the 3500 Monitoring System for complete vibration analysis.

Installation Guidance and Operational Benefits

Installing this proximity probe requires a 14 mm wrench and standard mounting brackets suitable for the threaded case. The threaded body enables precise gap adjustments using the supplied locking nut mechanism. Routine inspections of the cable jacket and connector pins will maintain long-term signal integrity. This probe excels in predictive maintenance strategies where early fault detection minimizes unplanned downtime. For best accuracy, calibrate the system against AISI 4140 steel targets to match the factory calibration curve. The extended 16.0 meter cable offers exceptional flexibility for remote mounting locations away from the machine train.
