Electrical Resistance Probe Retrievable with Large Adjustable Flush Element for 2” Access Systems

These probes are ideally suited for applications where the probe element needs to be flush with the wall of the pipe to prevent any obstructions.

Model ER7220 is an adjustable-length, flush mount, retrievable, electrical resistance probe

Model ER7220 is an adjustable-length, flush mount, retrievable, electrical resistance probe for use with the 2" access system in high pressure and high temperature applications. These probes are ideally suited for applications where the probe element needs to be flush with the wall of the pipe to prevent any obstructions.

The probe assembly consists of an insertion rod with an element, a hermetically sealed connector and a hollow plug nut, 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 a minimum of 1.75" up to any length in 1" increments (specify lengths over 1.75" as 2", 3", 4", etc.) specified by the customer using the formula below. The adjustable flush element allows for a total adjustment of 1".
