Bently Nevada CA21000-00-00-00-036-01-02 Explosion-Proof Housing Assembly

Product Overview

The CA21000-00-00-00-036-01-02 explosion-proof housing assembly from Bently Nevada is engineered for hazardous industrial environments where vibration probes and proximity transducer systems require certified mechanical protection. This housing assembly supports installation in refinery compressor trains, gas turbine skids, offshore platforms, petrochemical pumping stations, and power generation facilities exposed to combustible gas atmospheres.

The enclosure uses an aluminum main body combined with a 304 stainless steel sleeve to improve corrosion resistance and long-term structural stability in high-vibration process areas. Its 3.6 in probe penetration depth allows stable sensor routing inside explosion-proof junction locations while maintaining secure mechanical isolation. The assembly helps reduce unplanned downtime by protecting signal transmission hardware from contamination, mechanical damage, and hazardous-area exposure. Bently Nevada designed this unit for integration with industrial vibration monitoring architectures where compliance, durability, and maintenance accessibility remain critical operational requirements.

Suffix Breakdown

Engineering Construction Details

The housing assembly uses a flameproof mechanical structure suitable for classified hazardous zones commonly found in oil and gas processing facilities. The aluminum enclosure reduces total installation weight while the stainless steel sleeve improves resistance against moisture, salt spray, lubricants, and process contaminants.

The 3/4-14 NPT mounting interface supports direct installation into standard industrial conduit systems. The supplied explosion-proof fitting and sealing plug simplify field wiring configuration while maintaining enclosure integrity. The assembly supports compatibility with multiple Bently Nevada proximity probe configurations used in TSI and rotating machinery monitoring systems.

Technical Specifications

Frequently Asked Questions

Can this housing assembly operate in hazardous refinery environments?

Yes. The assembly is designed for explosion-proof installations in hazardous industrial areas including refineries, gas compression stations, and offshore platforms.

Does the unit include a proximity probe or extension cable?

No. This configuration specifies no probe and no extension cable. The housing assembly is supplied as a mechanical protection enclosure only.

Which mounting thread does this model use?

This version uses a 3/4-14 NPT threaded mounting interface for industrial conduit compatibility.

Can the enclosure support older Bently Nevada monitoring systems?

Yes. The assembly supports integration with many legacy and modern Bently Nevada proximity transducer installations used in rotating machinery monitoring systems.

Installation Guidance and Field Recommendations

Before installation, verify that the conduit entry thread matches the site hazardous-area specification and sealing requirements. Incorrect thread engagement may compromise explosion-proof integrity.

Use corrosion-resistant conduit sealing compounds in offshore or chemical processing environments where moisture intrusion and vapor exposure are common. Maintain proper grounding continuity between the housing assembly and plant grounding infrastructure.

During probe routing, avoid excessive cable bending inside the enclosure cavity. Sharp bending radius conditions can shorten probe cable service life and increase signal instability during long-term machine vibration monitoring.

For high-temperature turbine enclosures, maintain adequate spacing from process heat sources to reduce thermal stress on internal sensor connections and sealing components.
