Model ER7100 is a fixed-length, retrievable, electrical resistance probe for use with HPTM and MHTM high pressure access systems. The all-welded construction of the element makes it ideal for harsh environments. The probe assembly consists of an insertion rod with an element, a hermetically sealed connector, and a hollow plug nut, which are all welded in place. A velocity shield can be added to the assembly if required. The hollow plug nut on the probe screws into the hollow plug of the access system. This allows the probe to be installed in the process, using a retriever tool and service valve, without process shutdown. The insertion length (I.L.) can range from 5" up to any length specified by the customer in 1/8" increments. Insertion length is calculated by the formula:
I.L. = PD + WT + 1.75"
(where PD = penetration depth, WT = wall thickness)Note: Formula valid for access fitting heights of 5.25" (HP) and 5.5" (MH).
Several standard elements are available to meet your specific needs. Probe adaptors are
available and must be ordered separately.
