Model ER7300

Electrical Resistance Probe, Retrievable Spiral Loop
for High Pressure (HPTM and MHTM) Access Systems

View PDF version




 

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).
