Roxar Sacrificial Probe
The Roxar Sacrificial Probe is based on a closed tube with a defined wall thickness that is connected to a pressure measurement device. The effects of sand or solids will eventually erode through the sensing element of the Roxar Sacrificial Probe and expose the sealed system to the working pressure of the line. The pressure then passes through a nipple or a valve assembly and registers on a pressure gauge. The Roxar Sacrificial Probe solution is available with two options: Retrievable sacrificial probe and non-retrievable sacrificial probe. The retrievable solution can be removed and replaced under full operation with the support of the Roxar Mechanical Retriever Tool or the Roxar Hydraulic Retriever Tool. The non-retrievable solution is available in a fixed configuration and can only be removed and replaced when the process line is not exposed to pressure.
