The Endress+Hauser FMR54 is a premium 26 GHz non-contact radar level transmitter engineered for extreme high-temperature applications up to +450°C. Featuring a robust horn antenna with graphite sealing, it delivers ±2 mm accuracy across a 40 m range. Heartbeat Technology enables continuous self-diagnostics and traceable in-situ verification without process interruption. With HART, PROFIBUS PA, and Ethernet/APL communication, the FMR54 integrates seamlessly into modern control systems. Ideal for molten salt, hot oil, and steam drum level measurement in power plants, refineries, and chemical reactors.
