Bently Nevada 330905-12-22-05-02-05 3300 XL NSv Proximity Transducer System

Bently Nevada 330905-12-22-05-02-05 3300 XL NSv Proximity Transducer System

The Bently Nevada 330905-12-22-05-02-05, also cataloged as the 3300 XL NSv Proximity Transducer System, operates as a dedicated hardware component for measuring shaft displacement through eddy-current sensing within machinery vibration and position monitoring systems.

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics Signal Processing

The 3300 XL NSv Transducer System uses an eddy-current sensing structure to convert shaft displacement into proportional electrical signals for machinery monitoring applications. The system provides an Average Scale Factor of 7.87 V/mm (200 mV/mil), matching the common output characteristics of eddy-current transducer systems.

The NSv design provides enhanced side-view capability and small target measurement characteristics compared with standard Bently Nevada 3300 XL-series 5 mm and 8 mm transducer systems. The system supports installations where mechanical clearance restrictions require compact probe dimensions and reduced target geometry.

The 3300 XL NSv system provides a 1.5 mm (60 mils) linear range, exceeding the linear range of the 3000-series 190 Transducer System. Proper probe scaling and gap voltage validation are required during commissioning to establish the correct measurement position between the eddy-current probe and shaft target.

The system architecture supports replacement applications for 3300 RAM Transducer Systems and 3000-series or 7000-series 190 Transducer Systems when configured with compatible NSv components.

Field Installation Guidelines

Install the proximity probe with correct mechanical alignment to the shaft target and verify that the available mounting space matches the probe unthreaded length and overall case length dimensions.

Route the miniature coaxial ClickLoc cable away from high-current wiring, switching equipment, and sources of electromagnetic interference. Maintain cable protection against vibration, abrasion, and mechanical loading.

Verify the probe installation gap and perform gap voltage validation before connecting the measurement channel to the monitoring system. Confirm signal scaling and polarity during commissioning to ensure correct displacement measurement.

For retrofit applications, verify compatibility between the existing extension cable, monitoring system input, and the selected 3300 XL NSv Proximitor Sensor before system activation.
