Bently Nevada 146055-50-02-00 3300 Ceramic Capped Reverse Mount Probe

How Can You Ensure Reliable Vibration Monitoring in Harsh Environments?

When unplanned downtime threatens your rotating machinery, accurate vibration measurement becomes critical. The Bently Nevada 146055-50-02-00 3300 Ceramic Capped Reverse Mount Probe delivers the precision and durability needed for continuous protection of turbines, compressors, and pumps. Designed for demanding industrial applications, this 5-meter probe integrates seamlessly with 3300 XL Proximitor systems to provide real-time shaft displacement data.

Technical Specifications Breakdown

The 146055-50-02-00 features a 3/8-24 UNF thread case made from AISI 304 stainless steel, ensuring robust mechanical integrity. Its alumina ceramic tip (Al2O3) withstands extreme conditions, with an operating and storage temperature range of -51°C to +177°C (-60°F to +351°F). The probe is rated to seal 34 Bar (500 psi) nitrogen, making it suitable for high-pressure environments. With a 5.0-meter integral cable and a Miniature ClickLoc coaxial connector, this model offers a length tolerance of +20%, -0% for flexible installation. The nominal DC resistance from center to outer conductor is 8.73 ± 0.70 ohms, ensuring consistent signal transmission.

Industry Applications

This reverse mount probe excels in steam turbine radial vibration monitoring, where its 1.52 mm (60 mils) linear range captures critical displacement data from 0.25 to 1.78 mm (10 to 70 mils). In centrifugal compressor applications, the 7.87 V/mm (200 mV/mil) incremental scale factor provides high-resolution feedback for early fault detection. The 146055-50-02-00 also supports hydroelectric generator thrust bearing monitoring, where its ceramic cap resists oil contamination and thermal stress.

Installation & Setup Guidance

Mount the probe using the 3/8-24 threaded case with a maximum thread engagement of 0.563 inches. Ensure the target surface is AISI 4140 steel for calibrated accuracy. The 5-meter cable is designed exclusively for use with the 5 m Proximitor Sensor – do not substitute with other lengths. Position the probe tip 0.25 mm from the target at rest to establish the linear range starting point. Use the Miniature ClickLoc connector for secure, quick connections in tight spaces.

Maintenance & Reliability

Inspect the probe cable and connector periodically for wear, especially in high-vibration zones. The ceramic tip resists abrasion, but verify the gap setting annually using the system’s output voltage. For high-pressure applications above 34 Bar, consult Bently Nevada’s custom design department for pressure seal testing. The 146055-50-02-00 operates reliably across temperature classifications from T1 to T5, as detailed in the temperature schedule.
