Model ER7300 spiral loop probe is a retrievable, electrical resistance probe designed for use with both the HPTM and MHTM 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 gas transmission.
- Wide spacing of element loops - minimizes the risk of iron sulphide scaling and bridging.
While the spiral loop probe is ideally suited to fast flowing, sour systems, its high stability makes it a suitable choice for all 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, using the formula:
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).
