Bently Nevada 146054-011-20-02-05 Ceramic-Capped Proximity Probe
An unarmored ceramic-tip probe with a 1.1-inch case, two-metre lead, standard ClickLoc cable and multiple approvals.
Overview
146054-011-20-02-05 is a forward-mount 3300 ceramic-capped probe for non-contact machinery measurement where the front of the probe can encounter corrosive gases or liquids. Its alumina ceramic cap and stainless-steel case protect the sensing end.
The complete order code identifies the 1.1-inch case, two-metre total length, standard cable without connector protector and the multiple-approval option.

Features
- Alumina ceramic cap protects the front interface in aggressive chemical service.
- Ceramic-to-metal joints are helium leak tested for a hermetic front seal.
- Compatible with the appropriate 3300 extension cable and Proximitor Sensor.
- Compact forward-mount body retains the documented 3/8-24 interface.
Applications
- Proximity monitoring around anhydrous ammonia and other extreme-pH media.
- Rotating machinery where corrosive gases or liquids reach the probe face.
- Documented 3300 measurement points requiring the two-metre unarmored execution.
Lifecycle
- Confirm the process medium is compatible with the full probe assembly, not only the ceramic tip.
- Protect the unsealed rear and cable entry from destructive media.
- Record the matching extension cable, Proximitor Sensor and monitor scaling.
- Set the probe gap without allowing the ceramic face to contact the target, then verify the complete signal chain.
FAQ
Why select 146054-011-20-02-05 instead of a conventional metal-tip probe?
Its ceramic front end is intended for aggressive chemical exposure that can attack standard probe construction.
Is the rear of 146054-011-20-02-05 sealed against process media?
No. The rear and cable entry must remain protected; only the documented front ceramic-to-metal interface is designed for the stated exposure.
What system components must match 146054-011-20-02-05?
Confirm the extension cable, 3300 Proximitor Sensor, total electrical length, target material and monitor-channel scaling.
Does the approval suffix on 146054-011-20-02-05 eliminate installation review?
No. Barriers, field wiring, enclosure and area-classification documents must also comply with the site design.
What mechanical details should be checked before ordering 146054-011-20-02-05?
Verify the 3/8-24 holder, 1.1-inch case reach, cable route, bend radius and connector clearance.
What evidence should accompany a 146054-011-20-02-05 quotation request?
Provide the complete label, process medium, pressure, temperature, installed electronics and clear photographs of the probe and mounting point.
