The OPTIFLEX 8200 is a 2-wire guided radar level transmitter based on the Time Domain Reflectometry (TDR) technology. It is designed for level and interface measurement under extreme conditions in the power, oil and gas industries. Using an algorithm called "Dynamic Gas-phase Compensation (DGC)", the device measures accurately and without increased blocking distance the level of products in processes where the composition of the gas above the product can change suddenly (e.g. in steam boilers).
Show more For high safety requirements in applications with dangerous media, the OPTIFLEX 8200 features a single or double ceramic process seal system. Various converter and electronic versions like a remote converter or a sensor extension facilitate the access to the device. The level transmitter has approvals for use in hazardous areas.
