Technical Specifications Breakdown

Key parameters for the 21000-00-00-00-042-03-02 are listed below for quick reference:

Industry Applications for Enhanced Reliability

This housing assembly is ideally suited for rotating machinery monitoring in oil and gas, petrochemical, and power generation facilities. Its CSA explosion-proof certification makes it a preferred choice for hazardous areas classified as Class I Divisions 1 and 2 Groups C and D, Class II Divisions 1 and 2 Groups E, F, and G, and Class III. The design fully complies with API 670 Standard for externally mounted proximity probe housings, ensuring compatibility with industry best practices.

Installation and Setup Guidance

When installing the 21000-00-00-00-042-03-02, ensure the mounting thread (3/4-14 NPT) is properly sealed to maintain enclosure integrity. The assembly includes a dome cover that screws into the body, threaded ports for conduit connections, and a probe sleeve of optional length. Use the provided cable seal grip with grommets for cable sizes ranging from 1/8 to 3/16 inches, 1/4 to 5/16 inches, or 5/16 to 3/8 inches. Verify that the housing is correctly oriented to avoid stress on the probe cable.

Maintenance and Reliability

Periodically inspect the housing for signs of corrosion or damage, especially in corrosive environments. The aluminum body with 304 stainless steel sleeve offers good resistance, but regular checks ensure long-term reliability. Verify that all O-rings and seals remain intact to maintain the CSA Type 4 enclosure rating. The housing is rated for ambient temperatures from -50°C to +80°C (T4 rating) or -50°C to +40°C (T5 rating), so ensure the operating environment stays within these limits.

Robust Protection for Critical Vibration Monitoring

When machinery uptime and safety are paramount, the Bently Nevada 21000-00-00-00-042-03-02 provides a rugged, certified enclosure for proximity probes in harsh industrial environments. This housing assembly is engineered to protect sensitive vibration sensors while maintaining reliable, accurate measurements in demanding applications.

Compatibility and Integration

The 21000 housing is designed for use with Bently Nevada proximity probes and can be ordered with hazardous area approved probes for intrinsically safe applications. It is compatible with both 21000 aluminum and 24701 stainless steel housings. The assembly is RoHS compliant (Directive 2011/65/EU) and supports non-incendive circuits when connected per drawing 140979.
