Bently Nevada 21000-34-00-15-028-04-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-34-00-15-028-04-02 are listed below for quick reference:

Industry Applications: Hazardous Area Vibration Monitoring

The CSA Type 4 enclosure and explosion-proof rating allow direct installation in Class I, Division 1 hazardous areas, eliminating the need for additional purging or barriers. The 1.5-inch standoff adapter provides optimal clearance for probe installation, while the 2.8-inch probe penetration ensures the sensor tip reaches the target shaft surface reliably.

Installation & Setup Guidance

Mount the housing using the 3/4-14 NPT thread option, which must be selected when the standoff adapter is not zero length. Ensure the conduit connection uses the provided 3/4-14 NPT plug for a sealed installation. The aluminum body with a 304 stainless steel sleeve resists corrosion in wet or chemical-laden environments. When routing the probe cable (1.0 m length), avoid sharp bends to maintain signal integrity. Always verify the probe's part number and serial number are visible before final assembly.

Maintenance & Reliability

Periodically inspect the housing for signs of corrosion or mechanical damage, especially in high-vibration applications. Check the O-rings and thread seal for integrity to maintain the explosion-proof rating. The stainless steel sleeve provides long-term durability, but the aluminum body may require protective coating in highly corrosive atmospheres. No internal disassembly is needed for routine inspection; focus on external condition and cable connections.

Reliable Protection for Critical Machinery Monitoring

When protecting rotating assets in harsh industrial environments, the enclosure housing the proximity probe is as vital as the probe itself. The Bently Nevada 21000-34-00-15-028-04-02 Proximity Probe Housing Assembly is engineered to provide a secure, explosion-proof environment for a 3300 XL 8 mm probe, ensuring consistent, accurate vibration and position measurements in hazardous locations. This assembly is built for demanding applications such as steam turbines, compressors, and large pumps where safety and reliability are non-negotiable.

Compatibility & Integration

The housing accepts a 3300 XL 8 mm probe with connector protector, supporting selectable hazardous area approvals. It is fully compliant with API 670 standards for externally mounted proximity probe housings. The CSA certification covers both the housing and the probe for intrinsically safe applications when ordered with appropriate options.
