Model LP7300

CorrTran Style 3-Electrode LPR Probe
Retrievable for High Pressure (HP™ and MH™) Access Systems

Model LP7300 is a fixed-length, linear polarization resistance probe for use with HP™ and MH™ high pressure access systems and is specifically designed for use with CorrTran style instruments. 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 retrieval 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).

Electrodes are available in a wide variety of alloys and are sold separately (see Optional Accessories). Probe adaptors are also available and must be ordered separately.
