Model ER7230 is a fixed-length, flush-mount, retrievable, electrical resistance (ER) probe for use with high pressure access systems. The ER7230 is ideally suited for applications where the probe element should be flush with the wall of the pipe, but it can be used at any position in the line. The ER7230 has been specifically designed to minimize the negative effects of iron sulfide by maximizing the spacing between the sensing element and probe body, thus reducing the possibility of shorting by conductive buildup.
The probe assembly consists of the sensing element, insertion rod, hermetically sealed connector, and an integral hollow plug nut which mates with the hollow plugs of various high pressure access systems. This allows the probe to be installed and retrieved without system shutdown using a retriever tool and service valve.
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).
