Model LP7100 is a fixed-length, linear polarization resistance probe for use with HPTM and MHTM high pressure access systems. The probe assembly consists of an insertion rod with a hermetically sealed three-electrode endcap, a hollow plug nut, and a standard six-pin connector, which are all welded in place. 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. Several standard electrodes are available to meet your specific needs. Probe adaptors are also available and must be ordered separately. The insertion length (I.L.) can range from 2.000" up to any length specified by the customer in 1/8" increments, using the formula below:
I.L. = PD + WT + 1.75
(where PD = penetration depth, WT = wall thickness)
Note: I.L. does not include electrode length (see Alloy Chart below).
Note: Formula valid for access fitting heights of 5.25" (HP) and 5.5" (MH).
