The 21000-16-05-00-135-03-02 is rated explosion proof for hazardous areas. It carries CSA approvals and is certified as a CSA Type 4 enclosure. This assembly fully complies with API 670 Standard for externally mounted proximity probe housings.

Applications and Use Cases

Maintenance engineers rely on the 21000-16-05-00-135-03-02 for critical rotating machinery. It monitors shaft vibration in compressors, turbines, and pumps. The explosion-proof rating makes it ideal for oil and gas facilities. Its CSA Type 4 enclosure withstands washdown environments. This model also supports intrinsically safe applications when paired with approved probes.

Installation and Setup

Mount the housing using the 3/4-14 NPT thread option. Ensure the probe sleeve penetrates exactly 13.5 in for correct gap setting. Use the provided cable seal grip with the appropriate grommet for your cable diameter. Tighten the dome cover securely to maintain the explosion-proof seal. Always follow the manufacturer's manual for wiring and grounding.

Maintenance and Reliability

Inspect the O-rings and thread seal periodically for wear. Check the probe cable for damage at the connector. The stainless steel sleeve resists corrosion in moist environments. Regular inspection per the manufacturer's safety manual ensures long service life. This assembly reduces unplanned downtime by providing consistent vibration data.

Compatibility and Integration

The 21000-16-05-00-135-03-02 works with Bently Nevada monitoring systems. It accepts standard proximity probes for shaft vibration and position measurement. The 3/4-14 NPT fitting connects to common conduit systems. Use the included reducer for 1/2-14 NPT conduit. This housing integrates easily into existing API 670-compliant installations.
