Model ER1000 is a fixed-length, electrical resistance probe with a 1/2" NPT pipe
plug. The probe requires process isolation or process shutdown to install and a threaded
pipe fitting to mount. With a diameter of 1/2", the probe is ideal for applications
where space is limited. The probe assembly consists of an insertion rod with an element, a
hermetically sealed connector, a 1/2" NPT pipe plug, and a velocity shield, which are
all welded in place. The insertion length (I.L.) is calculated to the end of the shield
and can be specified by the customer. For standard probes, the maximum insertion length is
given in the chart below. Several standard loop elements are available to meet your
specific needs.
