Industry Applications

In a typical turbomachinery monitoring scenario, a plant engineer needs to measure shaft vibration within a linear range of 1.52 mm (60 mils). The 146055-50-02-00, when used with the 5 m Proximitor Sensor, delivers an incremental scale factor of 7.87 V/mm (200 mV/mil) over the full linear range. This allows operators to detect early signs of bearing wear or imbalance before they lead to unplanned downtime. Common applications include steam turbines, centrifugal compressors, pumps, and gearboxes where reverse mount configuration is required.

Installation & Setup Guidance

For optimal performance, mount the probe with the 3/8-24 thread into a compatible probe holder. Ensure the target surface is clean and made of AISI 4140 steel for calibrated accuracy. The maximum length of thread engagement is 0.563 inches. When routing the 5.0 meter coaxial cable, avoid sharp bends and contact with hot surfaces. The probe operates reliably from -51°C to +177°C, making it suitable for both cold climates and high-temperature machinery casings.

Maintenance & Reliability

The alumina ceramic (Al2O3) probe tip resists wear and corrosion, extending service life in demanding environments. The AISI 304 stainless steel case provides mechanical robustness. Periodic inspection of the cable and connector for damage is recommended. The probe is rated to seal 34 Bar (500 psi) nitrogen, ensuring reliable operation in pressurized applications. For high-pressure environments, contact Bently Nevada for modifications.

Selection Guide & Purchasing Advice

Before ordering, verify that your system requires a 5.0 meter integral cable and a Miniature ClickLoc coaxial connector. The 146055-50-02-00 is designed for use with the 5 m Proximitor Sensor only. For other cable lengths (0.5, 1, 2, or 9 meters), select the appropriate part number suffix. BluePLC Industrial stocks this probe in new and original factory packing with full warranty.
