Industry Applications for Reliable Machinery Protection
The 4-inch probe penetration allows for deep insertion into bearing housings, while the 3/4-14 NPT mounting thread ensures a secure, leak-proof installation. The included fittings kit simplifies conduit connections, reducing installation time. By providing a stable, sealed environment for the 3300 XL 8mm probe, this assembly helps prevent false trips and unplanned downtime.

Installation & Setup Guidance
When installing the 24701-28-05-00-040-03-02, ensure the mounting surface is clean and free of debris. Apply thread sealant to the 3/4-14 NPT threads before installation. The cable seal grip accommodates cable diameters from 1/8 to 3/8 inches; select the appropriate grommet for your cable. Verify that the probe tip is positioned correctly relative to the shaft target surface, following the probe manufacturer's gap setting specifications. Do not overtighten the dome cover to avoid damaging the O-rings.
Maintenance & Reliability
Periodically inspect the housing assembly for signs of corrosion or mechanical damage. Check that all conduit fittings are tight and the cable seal grip is properly compressed. The 303 stainless steel body and 304 stainless steel sleeve offer corrosion resistance in most industrial environments. Replace O-rings if leakage is suspected. No internal maintenance is required; the assembly is designed for long-term, maintenance-free operation.
