Bently Nevada 330105-02-12-10-02-05 Vibration Probe

Technical Specifications Summary

The Bently Nevada 330105-02-12-10-02-05 is a specialized reverse mount proximity sensor belonging to the 3300 XL 8mm Transducer System. This device measures shaft vibration and axial position without making physical contact. Technicians typically install this specific model in applications where they must mount the probe from the inside of a machine housing or through a specialized bracket. By utilizing eddy current technology, the probe provides highly accurate displacement data. This information is vital for identifying mechanical faults like shaft rub, imbalance, and bearing degradation.

Operational Performance

This reverse mount probe offers a linear range of 2.0 mm (80 mils). It generates a standard output signal of 7.87 V/mm (200 mV/mil) when connected to a 3300 XL Proximitor. Because it uses advanced temperature compensation, the sensor maintains precision even during significant thermal shifts. Furthermore, the probe tip features a robust polyphenylene sulfide (PPS) material. This allows the sensor to survive in environments saturated with industrial oils, steam, and high-pressure chemical vapors.
