Model ER4100 is a retractable, electrical resistance probe commonly used in field and
plant applications. The all-welded design allows the probe to be used in harsh
environments. A specially designed packing gland is used with the probe for insertion into
or retraction from a pressurized system without a process shutdown. Standard packing
material in the packing gland is Teflon®, however, grafoil packing can be
provided for high temperature applications*. When the probe element requires replacement,
the packing gland assembly may be reused. (Probe packing should also be replaced at this
time.) The probe is designed to mount onto a 1" piping system, but can easily be
adapted to fit your specific requirements. The probe assembly consists of a replaceable
insertion rod with an element, a hermetically sealed connector welded in place, and a
packing gland. A safety chain and safety nut are also provided to prevent blowout. 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.
