Applications & Use Cases

This housing assembly is ideal for rotating machinery monitoring in refineries, power plants, and chemical facilities. It meets API 670 standards for externally mounted proximity probes. The CSA Type 4 enclosure rating makes it suitable for harsh, wet environments. Consequently, it helps prevent unplanned downtime by detecting shaft vibration early.

Installation & Setup

Mount the housing using the 3/4-14 NPT thread. Ensure the probe penetration depth is set to 5.0 in. Use the provided cable seal grip with grommets for cable sizes from 1/8 to 3/8 inches. Verify the O-rings are seated properly to maintain the explosion-proof seal. Always follow the manufacturer's manual for torque specifications.

Maintenance & Reliability

Inspect the housing periodically for signs of corrosion or damage. Check the cable seal grip and grommets for wear. Replace O-rings if they become brittle. Regular maintenance extends service life and ensures consistent performance. The aluminum and stainless steel construction resists corrosion in most industrial environments.

Compatibility & Integration

The 21000-16-05-00-050-03-02 works with Bently Nevada monitoring systems that accept 3300 XL 8 mm probes. It is fully compliant with API 670 standards. The CSA Type 4 enclosure rating ensures compatibility with hazardous area installations. For system integration, consult the Bently Nevada documentation.
