Probe penetration reaches 5 in. The fitting option includes one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and a cable seal grip with grommets for cables from 1/8 to 3/8 inches. The mounting thread option is 3/4-14 NPT. Typical weight is 1.1 kg (2.4 lb) without fittings.

Applications and Use Cases

In oil and gas refineries, the 21000-28-05-15-050-03-02 monitors shaft vibration on compressors and turbines. Its CSA Type 4 enclosure rating makes it suitable for outdoor and washdown areas. The assembly fully complies with the API 670 Standard for externally mounted proximity probe housings. For power generation plants, this housing provides reliable data for predictive maintenance programs.

Installation and Setup Guidance

Mount the housing using the 3/4-14 NPT thread option for secure attachment. Select the appropriate grommet size from the included set to match your cable diameter. Ensure the probe sleeve length aligns with your machine clearance requirements. Always follow Bently Nevada's installation manual for proper probe gap setting and torque values.

Maintenance and Reliability Tips

Inspect the O-rings and thread seal periodically to maintain the explosion-proof integrity. Verify that all conduit fittings remain tight after initial installation. The aluminum and stainless steel construction resists corrosion in most industrial environments. Regular inspection per the manufacturer's safety manual helps ensure long-term reliability.
