Model LP7000

Linear Polarization Resistance Probe
Retrievable with 2-Electrode Endcap
for High Pressure (HP™ and MH™) Access Systems

Model LP7000 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 two-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. The insertion length (I.L.) can range from 3.000" up to any length specified by the customer in 1/8" increments, using the formula below. (This includes 1.25" for the length of the electrode.)

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 electrodes are available to meet your specific needs. Probe adaptors are also available and must be ordered separately.
