Model LP7210

Linear Polarization Resistance Probe
Retrievable with Flush-Mount 3-Electrode Endcap
for High Pressure (HPTM and MHTM) Access Systems


lp7210.gif (4386 bytes)

 

Model LP7210 is a fixed-length, flush-mount, three-electrode, retrievable, linear polarization resistance probe for use with HPTM and MHTM high pressure access systems. These probes are ideally suited for applications where the probe electrodes need to be flush with the wall of the pipe. The probe assembly consists of an insertion rod, a flush-mount three-electrode endcap, and a six-pin military connector. 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 probe's three-electrode endcap is filled with an epoxy seal. Electrodes are not replaceable. The insertion length (I.L.) can range from a minimum of 1.75" up to any length specified by the customer in 1/8" increments, using the formula: 

I.L. = PD + WT + 1.75"
(where PD = penetration depth, WT = wall thickness)
For top-of-the-line, flush-mount monitoring, PD = 0.

Note: Formula valid for access fitting heights of 5.25" (HP) and 5.5" (MH).
