What Does This Probe Housing Assembly Include?

Each assembly arrives new and original in factory packing. The housing body is aluminum with a 304 stainless steel sleeve, and the assembly weighs 1.1 kg (2.4 lb) typical without fittings. The dome cover screws into the housing body, and threaded ports accept conduit connections. O-rings and a thread seal support dependable sealing, while the reverse mount probe and optional standoff adapter simplify installation and service access.

This configuration carries a 1.0 m (39 in) probe cable and a 6.6 in probe penetration. The 3.0 in standoff adapter pairs with a 3/4-14 NPT mounting thread. Fitting option 03 provides one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and a cable seal grip with grommets for cable sizes from 1/8 to 3/8 inches.
