Description：

The Bently Nevada 330105-02-12-10-12-RU is a 3300 XL 8 mm Reverse Mount Proximity Probe developed for precision shaft monitoring in critical rotating machinery. As part of the proven 3300 XL 8 mm Proximity Transducer System, this probe is used to capture non-contact measurements of shaft movement, helping operators monitor machine condition and protect valuable equipment during continuous operation.

Integrated with a compatible 3300 XL extension cable and Proximitor Sensor, the 330105-02-12-10-12-RU forms a complete monitoring solution capable of measuring radial shaft vibration, axial thrust position, shaft displacement, rotor eccentricity, and Keyphasor® or speed reference signals. The resulting data can be used by machinery protection systems and condition monitoring platforms to support predictive maintenance and operational reliability.

Frequently asked questions

Q : What does the complete model number 330105-02-12-10-12-RU mean?

It is a 3300 XL 8mm reverse mount probe, unarmored, with FluidLoc/ClickLoc cable, 1.0-meter length, specific reverse threads, and Russian/Eurasian zone certification.

Q : What is the exact linear range of this 8mm probe?

The linear range is 2.0 mm (80 mils), operating between 0.25 mm (10 mils) and 2.25 mm (90 mils) away from the target.

Q : Can this probe be used on a shaft made of stainless steel?

Yes, but standard calibration is for AISI 4140 steel. Stainless steel requires a custom-calibrated Proximitor or manual correction of the scale factor.

Q : What is the maximum temperature rating for the probe tip?

The polyphenylene sulfide (PPS) probe tip and cable are rated for continuous operation from -51 °C to +177 °C (-60 °F to +350 °F).
