Model ER2100 is a fixed-length, electrical resistance probe with a 3/4" 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 harsh
environments. The probe assembly consists of an insertion rod with an element, a
hermetically sealed connector, and a 3/4" NPT pipe plug, which are all welded in
place. A velocity shield can be provided if required. The insertion length (I.L.) is
calculated to the end of the shield or to the end of the element if a shield is not
present. Probe length can be specified by the customer. For standard probes, the maximum
insertion length is given in the chart below. Several standard elements are available to
meet your specific needs.
