Model ER-2000 wire/tube/strip-loop, electrical Resistance Probe is a fixed-length probe for use with the 2” access system in high pressure and high temperature applications. The wire loop design is highly sensitive and performs well in locations subject to electrical or system noise. Element thickness offers longer probe life compared to other types. Two sizes of elements are available to suit requirements regarding sensitivity and desired probe life. A velocity shield can be added to the assembly if required. ER probe body is manufactured from 316 stainless steel with AISI 1018 mild steel element. Probe bodies and elements are available in alternative materials upon request. Standard probes are designed for mounting through a Hollow Plug assembly. This allows the probe to be installed in the process, using a retriever tool and service valve, without process shutdown.
