Industry Applications

Engineers use the 21000-34-05-00-030-03-02 in rotating machinery monitoring. It works well in pumps, compressors, and turbines. The housing is certified as CSA Type 4 enclosure. It is also fully compliant with API 670 Standard for externally mounted proximity probe housings. This makes it suitable for hazardous areas where explosion-proof ratings are required.

Installation Guide

Mount the assembly using the 3/4-14 NPT thread. Ensure the probe cable length of 0.5 m is sufficient for the routing path. Use the provided fittings for conduit connections. The standoff adapter option is not used here, so direct mounting is possible. Always follow the manufacturer's manual for proper torque and sealing.

Routine Care

Inspect the housing periodically for signs of wear or corrosion. The aluminum body and stainless steel sleeve resist harsh environments. Check the O-rings and thread seal during maintenance. Replace any damaged fittings to maintain the explosion-proof rating. Regular inspection per manufacturer's safety manual ensures long service life.
