SIEMENS 7ML5050-0AA21-1DA0 - Radar Level Transmitter
The SIEMENS SITRANS LR250 7ML5050-0AA21-1DA0 is a compact, 2-wire, loop-powered radar level transmitter engineered for continuous non-contact level measurement of liquids and slurries in industrial process environments. Utilizing Frequency Modulated Continuous Wave (FMCW) radar technology, this device provides precise and reliable measurement data for integration into process control systems via a 4-20 mA output with HART communication. It is designed for general-purpose applications requiring robust and accurate level monitoring in storage tanks and process vessels.
