The Bently Nevada 330709-000-070-50-02-00 Proximity Transducer Probe monitoring module interfaces with the 3300 XL 11 mm Proximity Transducer System. This complete system, comprising a probe, extension cable, and Proximitor Sensor, provides a 3.94 V/mm (100 mV/mil) output for non-contact vibration and displacement measurement on fluid film bearing machines. Its large 11 mm tip offers a longer linear range than standard 8 mm systems.

This extended linear range makes the system, used with the 330709-000-070-50-02-00 Bently Nevada Sensor Proximity Probe Cable, ideal for critical applications such as axial position, differential expansion on steam turbines, and rod drop measurements on reciprocating compressors. It is also suitable for tachometer, zero speed, and Keyphasor signal duties. The 3300 XL 11 mm Proximitor Sensor is designed as a direct replacement for older 7200-series systems.

When upgrading to this new transducer system for the Proximity Transducer Probe Bently Nevada 330709-000-070-50-02-00, it is mandatory to replace every component, including the probe, cable, and sensor. Furthermore, the Proximity Probe Bently 330709-000-070-50-02-00 itself must be updated. For a 3500 Monitoring System, this requires an updated configuration software version that explicitly lists the 3300 XL 11 mm system as a compatible option.

The Proximitor Sensors for the Bently Nevada 3300 SERIES 330709-000-070-50-02-00 are factory-calibrated for AISI 4140 steel, with calibrations for other materials available upon request. Each 3300 XL extension cable includes silicone tape, which can be used as an alternative to connector protectors, though it is not advised for connections exposed to turbine oil.
