Model ER7300 - Electrical Resistance Probe

Electrical Resistance Probe Retrievable Spiral Loop for 2” High Pressure Access Systems

The element is a spiral wound strip encased in epoxy. This approach to element construction offers several advantages over other element geometries.

Model ER7300 spiral loop probe is retrievable, electrical resistance probe

Model ER7300 spiral loop probe is retrievable, electrical resistance probe designed for use with 2 inch high pressure access systems. The element is a spiral wound strip encased in epoxy. This approach to element construction offers several advantages over other element geometries:

High intrinsic resistance – provides highly stable readings with low susceptibility to noise.
High element strength – allows use in very high flow rate regimes such as a gas transmission.
Wide spacing of element loops – minimises the risk of iron sulphide scaling and bridging.

While the spiral loop is ideally suited to fast flowing, sour systems, its high stability makes it a suitable choice for oil and gas systems.

Insertion length (I.L.) can range from a minimum of 3.75” up to any length (in 1/8” increments) specified by the customer.
