Product Overview
When a turbine or compressor goes down, every hour of downtime hurts. The Bently Nevada 146054-08-50-00-05 is a 3300 ceramic capped proximity probe built for fast replacement in oil, gas and industrial automation systems. This exact model ships new and original in factory packing, so you can get your machine monitoring back online without delay.
This probe uses a 3/8-24 UNF thread, a 0.8 in case, and a 5.0 m total length. It is a non-armored probe with no connector, and it carries CSA, ATEX and IECEx agency approvals.

What These Specs Mean for Your Machine
The 5.0 m length pairs only with a 5 m Proximitor Sensor, so match it to your existing system before ordering. The ceramic tip resists wear in harsh service, while the AISI 304 stainless case stands up to oil and gas environments. With a linear range of 1.52 mm and an ISF of 7.87 V/mm, this probe delivers the measurement stability that 3300 systems are known for.
Applications and Integration
This probe suits steam and gas turbines, compressors and other rotating equipment where axial and radial position must be monitored. In a refinery, it can replace a failed probe on a critical compressor train without waiting weeks for a factory order. Because it carries CSA, ATEX and IECEx approvals, it fits classified areas where those certifications are required.
The 75 Ω coaxial cable integrates with standard 3300 Proximitor Sensor systems. If you are wiring into a plant network, confirm your extension cables and connection modules with your supplier first, since this probe has no connector and a fixed 5 m cable.
Selection and Maintenance Tips
Before you buy, verify three things: the 5 m length matches your Proximitor Sensor, the 3/8-24 thread fits your mounting, and your area classification accepts the -05 approval. For maintenance, inspect the probe tip periodically for wear and keep the cable free of sharp bends. Always follow the manufacturer’s safety manual for hazardous-area work.
