Product Description

To externally mount proximity probes, use one of these all-metal Proximity Probe Housing Assemblies: 21000 aluminum probe housing assembly, 24701 stainless steel probe housing assembly .The 21000, 24701, and 164818 Proximity Probe Housing Assemblies consist of the following parts:  A dome cover that screws into the body of the housing； Threaded ports for conduit connections；A probe sleeve of optional length；O-rings；A reverse mount proximity probe；A thread seal；Optional conduit fittings；An optional standoff adapter.

Application 

Centrifugal Compressor Plants: Installed on external high-pressure bearing housings, using a 3.3-inch penetration depth to pass through thick casings and protect internal vibration probes in real time.

Petroleum Refining Plants: Used for outdoor pump unit protection, where an aluminum body with stainless steel sleeve resists acidic atmosphere and oil mist corrosion.

Large Fertilizer Plants: Applied on ammonia synthesis compressor units, with NPT threaded interfaces ensuring tight sealing at casing connections to prevent process gas leakage.

Mining and Ore Processing Plants: Used in large ball mill drive system monitoring, serving as a physical guard against slurry splashes and heavy dust exposure.

Combined Cycle Power Plants: Installed on turbine auxiliary machinery systems, providing stable connection and transition space for 0.5-meter short cables.

Frequently Asked Questions

Q: What impact does the lack of a Standoff Adapter have on installation of the 21000-16-05-00-033-04-02?
A: It shortens cantilever length and enables direct 3.3-inch penetration, making installation more compact for limited-space housings.

Q: Why does the 21000-16-05-00-033-04-02 come with a 0.5 m pre-installed cable?
A: The short cable allows fast junction-box switching and avoids signal loss from long cable coiling in confined spaces.

Q: Will the aluminum body of the 21000-16-05-00-033-04-02 oxidize in petrochemical environments?
A: No. Industrial aluminum alloy with 304 stainless steel sleeves provides strong corrosion resistance.

Q: How is the measurement gap verified in the 21000-16-05-00-033-04-02?
A: Sleeve depth is adjusted externally while monitoring probe output voltage until the correct position is reached.

Q: Can the 3/4-14 NPT plug of the 21000-16-05-00-033-04-02 be replaced with an explosion-proof hose connector?
A: Yes, it is compatible with standard explosion-proof fittings and flexible metal hose connectors.
