Industry Applications
This Bently Nevada 146054-08-20-01-05 probe excels in turbomachinery, pumps, compressors, and motors where shaft vibration and position must be monitored continuously. Its ceramic tip resists wear and contamination, ensuring stable readings in dusty or humid environments. The 2.0-meter cable length (6.6 feet) suits typical machine train layouts, and the miniature coaxial ClickLoc connector simplifies installation.
Installation & Setup Guidance
For accurate measurement, mount the Bently Nevada 146054-08-20-01-05 with the probe tip positioned within the linear range (0.25 to 1.78 mm from the target). Ensure the thread engagement does not exceed 0.563 in. Use the ClickLoc connector to secure the cable, and route the cable away from high-EMI sources. Calibrate the system with an AISI 4140 steel target to maintain the specified incremental scale factor.
Maintenance & Reliability
Routine inspection of the probe tip and cable is essential. Check for physical damage, contamination, or loose connections. The ceramic cap resists abrasion, but inspect it periodically for cracks. Operate within the temperature range of -51°C to +177°C to ensure long-term reliability. The pressure seal is rated to 34 Bar (500 psi) nitrogen; for higher pressures, consult the custom design department.
Selection Guide & Purchasing Advice
Before purchasing, verify the overall case length (0.8 in), total length (2.0 meters), connector type (miniature coaxial ClickLoc), and agency approvals (CSA, ATEX, IECEx) match your application. The Bently Nevada 146054-08-20-01-05 is supplied new in factory packing with a 12-month warranty. PLC Source PRO offers this genuine module with fast worldwide shipping.
