Bently Nevada 21000-28-05-00-085-03-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-28-05-00-085-03-02 are listed below for quick reference:

Industry Applications for Reliable Monitoring

The CSA certification for Class I Divisions 1 and 2 Groups C and D, and Class II Divisions 1 and 2 Groups E, F, and G ensures safe operation in volatile environments. The 8.5 in probe penetration allows for precise positioning within machinery casings, reducing installation complexity and improving measurement accuracy.

Installation and Setup Guidance

When installing the 21000-28-05-00-085-03-02, ensure the mounting thread (3/4-14 NPT) is properly sealed to maintain the enclosure's integrity. The assembly includes a 3/4-14 NPT plug, a 3/4-14 to 1/2-14 NPT reducer, and a cable seal grip with grommets for cable sizes from 1/8 to 3/8 inches. Use the provided fittings to secure conduit connections and maintain the explosion-proof rating. The probe cable length of 0.5 m (20 in) should be routed without sharp bends to avoid signal degradation.

Maintenance and Reliability

Periodically inspect the O-rings and thread seal for wear to maintain the CSA Type 4 enclosure integrity. The aluminum body with 304 stainless steel sleeve resists corrosion in harsh industrial environments. For hazardous area installations, verify that the circuit is non-incendive when connected per drawing 140979. The housing is rated T5 @ Ta = -50°C to +40°C and T4 @ Ta = -50°C to +80°C, ensuring reliable operation across a wide temperature range.

Robust Protection for Critical Vibration Monitoring

Industrial rotating machinery demands reliable vibration monitoring to prevent catastrophic failures. The Bently Nevada 21000-28-05-00-085-03-02 Proximity Probe Housing Assembly provides a rugged, explosion-proof enclosure for proximity probes in hazardous environments. This assembly is designed for use with a 3300 XL 8 mm probe, offering selectable hazardous area approvals. It is fully compliant with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probe housings.

Compatibility and Integration

This assembly is designed for use with Bently Nevada 3300 XL 8 mm proximity probes. The reverse mount probe configuration simplifies installation in tight spaces. The optional standoff adapter (not included in this suffix code) can be added for specific mounting requirements. The housing is fully compliant with API 670, ensuring interchangeability with existing installations.

Selection Guide and Purchasing Advice

When selecting a proximity probe housing assembly, consider the probe cable length, penetration depth, and mounting thread requirements.
