Industry Applications
Turbine Monitoring
In steam and gas turbines, the 146054-08-10-00-05 measures shaft vibration and axial position. Its ceramic tip withstands high temperatures up to +177°C, ensuring reliable data in the turbine bearing housings.
Compressor Protection
Centrifugal and reciprocating compressors benefit from the probe's 1.52 mm linear range. Operators can set precise alarm thresholds to trigger maintenance before rubs or surge events cause damage.
Installation & Setup Guidance
Mount the probe using the 3/8-24 UNF thread into a properly tapped hole. Ensure the target surface is clean and made of AISI 4140 steel for optimal performance. Adjust the gap so the target sits within the linear range (0.25 to 1.78 mm from probe tip). Use the 75 Ω coaxial FEP cable for signal integrity. Do not exceed the maximum thread engagement of 0.563 inches to avoid mechanical interference.
Maintenance & Reliability
The alumina ceramic tip resists wear and chemical attack, extending service life in harsh environments. Periodically inspect the cable for cuts or abrasion, especially near the probe connector. Verify the pressure seal integrity if the probe is installed in a pressurized zone. Routine calibration checks against a known target ensure measurement accuracy.
Compatibility & Integration
This probe is part of the 3300 XL system and works with Bently Nevada Proximitor sensors and extension cables. The 75 Ω coaxial interface is standard for Bently Nevada monitoring systems. For systems requiring agency approvals, the -05 option includes CSA, ATEX, and IECEx certifications for hazardous locations.
Selection Guide & Purchasing Advice
Before ordering, confirm the overall case length (08 = 0.8 in) and total length (10 = 1.0 m) match your installation requirements. Verify the thread type (3/8-24 UNF) and agency approval needs.
