Product Overview
When a turbine or compressor train goes down, every hour of downtime costs money. The Bently Nevada 146054-08-90-01-05 is a 3300 ceramic-capped proximity probe built to keep radial vibration and axial position measurements running reliably in harsh oil, gas and industrial environments. This probe ships new and original in factory packing, ready for fast dispatch worldwide.

Why This Probe Configuration Works
The 9.0 m total length with a miniature coaxial ClickLoc connector suits installations where the Proximitor Sensor sits in a junction box some distance from the machine case. The ceramic tip resists wear and target contact better than plastic-capped alternatives, which matters on machines with tight clearances. With CSA, ATEX and IECEx approvals, this probe fits hazardous-area monitoring where certification is mandatory.
Applications
- Steam and gas turbines: radial vibration and axial thrust monitoring on large rotating trains.
- Centrifugal compressors: shaft displacement measurement in oil and gas processing.
- Pumps and motors: position feedback where a 9.0 m cable run reaches the Proximitor Sensor.
Installation Notes
Mount the probe through a 3/8-24 threaded hole and confirm the target is AISI 4140 steel for rated accuracy. Keep the linear range between 0.25 and 1.78 mm (10 to 70 mils) from the target. Route the FEP-insulated coaxial cable away from high-temperature zones beyond the probe’s rated range. For hazardous areas, follow the applicable approval documentation.
