Bently Nevada 21000-34-00-20-039-04-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-34-00-20-039-04-02 are listed below for quick reference:

Industry Applications: Protecting Critical Assets

The CSA Type 4 enclosure and explosion-proof rating (when ordered with appropriate options) make it suitable for hazardous areas per API 670 Standard.

Installation & Setup Guidance

Engineers should verify the mounting thread (3/4-14 NPT) matches the machine port. The standoff adapter length of 2.0 in and probe penetration of 3.9 in must be confirmed to achieve proper gap and linear range. Use the included 3/4-14 NPT plug for unused conduit entries to maintain enclosure integrity.

Maintenance & Reliability

Periodically inspect the aluminum body and 304 stainless steel sleeve for corrosion or damage. Check O-rings and thread seal during each maintenance cycle. The assembly's robust construction minimizes drift and extends service life.

Problem: Externally Mounted Proximity Probes Face Harsh Conditions

Rotating machinery monitoring demands robust probe housings that withstand vibration, moisture, and hazardous environments. Standard enclosures often fail to protect sensitive probes, leading to false readings and unplanned downtime.
