Model ER2013 (with wire/tube/strip-loop element) is a fixed-length with a ¾” NPT pipe plug. The probe requires process isolation or process shutdown to install and a threaded pipe fitting to mount. The all-welded construction allows the probe to be used in aggressive environments. The probe assembly consists of an insertion rod with an element, a hermetically sealed connector, and a ¾” NPT fitting, which are all welded in place. A velocity shield can be provided if required. ER probe body is manufactured from 316 stainless steel with an AISI 1018 mild steel element. Probe body and element are available in alternative materials upon request.
