Model ER3100 is an adjustable-length, electrical resistance probe with a 3/4" NPT
compression fitting. The compression fitting allows the probe to be inserted into the
process to the required length. 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 welded in place, a 3/4" compression
fitting, and a safety nut to prevent blow out. A velocity shield can be added to the
assembly 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.
