Overview Manuals Applications Installation & Integration Safety & Compliance Compatibility

Features:

  • 3/8-24 UNF threaded stainless steel case with an overall length of 5.8 inches.
  • Alumina ceramic tip (Al2O3) designed for high-pressure and extreme pH conditions.
  • Integrated 2.0-meter coaxial cable with gold-plated ClickLoc connector.
The 146054-058-20-02-05 MOD:173931-011-058 represents a factory-modified 3300 ceramic capped proximity probe, featuring an extended 5.8-inch AISI 304 stainless steel case and a 2.0-meter FEP-insulated coaxial cable.

Designed for machinery protection in harsh process environments, this probe unit transmits non-contact vibration and position signals through its helium-leak-tested ceramic-to-metal interface to a compatible Proximitor Sensor.

Installation requires precise electrical gapping to avoid mechanical contact with the target surface, and the unsealed rear portion of the assembly must be isolated from corrosive liquids or gases.

Availability,The 146054-058-20-02-05 MOD:173931-011-058 is fully surplus / newly original, verified and guaranteed by the manufacturer (OEM).

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the pressure rating of the 146054-058-20-02-05 MOD:173931-011-058 front tip?
The front-end ceramic-to-metal seal of the 146054-058-20-02-05 MOD:173931-011-058 is helium leak-tested and rated to seal pressure up to 34 Bar (500 psi) nitrogen.
Is the rear connection of the 146054-058-20-02-05 MOD:173931-011-058 sealed against fluids?
No, the 146054 series probes do not have a sealed rear fitting or stainless steel armor tube, so the rear of the 146054-058-20-02-05 MOD:173931-011-058 must not be exposed to corrosive gases or liquids.
What is the tightening requirement for the ClickLoc connector on 146054-058-20-02-05 MOD:173931-011-058?
The gold-plated ClickLoc connector on the 146054-058-20-02-05 MOD:173931-011-058 requires only finger-tight torque until it clicks, preventing accidental loosening without requiring special tools.
Which Proximitor Sensors and extension cables are compatible with 146054-058-20-02-05 MOD:173931-011-058?
The 146054-058-20-02-05 MOD:173931-011-058 is fully compatible with Bently Nevada 3300 Proximitor Sensors and matching 75 ohm extension cables configured for a 5-meter or 9-meter overall system length.
What should be considered when setting the gap for 146054-058-20-02-05 MOD:173931-011-058?
Set the gap electrically to the recommended 1.0 mm (40 mils) setting without making direct mechanical contact with the shaft, as the ceramic tip cannot withstand direct physical impact.
How can I request a quotation or check availability for 146054-058-20-02-05 MOD:173931-011-058?
You can submit an inquiry directly through our sales contact form with the full part number 146054-058-20-02-05 MOD:173931-011-058 to receive real-time pricing, stock status, and lead time details.
