Model ER7210-ME

Special* ER Probe with Flush Element
Retrievable Type for use in High Pressure (HPTM and MHTM) Access Systems

View data sheet (PDF)


Model ER7210-ME series of probes operates based on the ER technique, and is specially designed for use with high resolution instruments from other suppliers. Model ER7210-ME probes are manufactured using superior materials and techniques to provide improved performance. Better potting materials ensure greater stability by improving heat-transfer efficiency, while laser-welded wire connections extend the functional temperature range of the probe, and ensure reliable, low-resistance connections. In addition, Model ER7210-ME flush probes are encapsulated using Ryton® PPS which provides excellent chemical resistance, thermal stability, and strength.

Model ER7210-ME is a fixed-length, flush-mount, retrievable probe for use with HP™ and MH™ high pressure access systems. This allows the probe to be installed in the process, using a retrieval tool and service valve, without process shutdown. 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).

The flush-mount element is ideally suited for applications such as pigged pipelines or high-flow systems where the probe face needs to be flush with the wall of the pipe.

* Model ER7210-ME is designed to be compatible with high-resolution or "high speed" instruments from other manufacturers. For the Metal Samples standard probe see model ER7210.
