Model ER3000 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 probe consists of an insertion rod
with an element, a hermetically sealed connector, 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.
