Model ER3200 is an adjustable-length, electrical resistance probe with a 3/4" NPT
compression fitting combined with a 3/4" to 1 1/2" adapter. 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 probe assembly consists of an insertion rod with an element, a hermetically
sealed connector welded in place, a 3/4" compression fitting, and a 3/4" to 1
1/2" adapter. The adapter can not be removed from the compression fitting. The
insertion length (I.L.) is calculated to the end of the element. 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.
