EuropCorr Tubular ER Probe

The Tubular ER probe offers a large measuring surface, the fastest dynamic response to temperature transients and the lowest sensitivity to conductive deposits such as FeS. The thin-walled tubular element is protected by a shield (AISI 316L + PTFE). Five element thicknesses suit different applications; probe life is 50% of the element thickness.

Electrical Resistance (ER) probes measure the increase in resistance of a corroding metal element exposed to the process: as corrosion reduces the element cross-section, resistance rises, and metal loss over time gives the corrosion rate. A reference element at the same temperature, not exposed to the medium, compensates temperature effects. ER probes work in almost any environment, including high-resistivity media where electrochemical methods fail; they respond much faster than weight loss coupons, stay installed until their life is used up, can be correlated to process parameters and can trigger alarms. Thinner elements react faster to upsets; thicker elements last longer where corrosion rates are low to medium.

The probe is mounted through a EuropCorr Hollow Plug Assembly and is used with both 2" high-pressure mechanical and hydraulic access systems; with the Retrieval Tool and Service Valve it can be changed or inspected without shutdown. Readings are taken with the MaxiCorr portable instrument through the 6-pin connector (S-type connector on request) or continuously with the MegaCorr data logger.
