PRODUCT DESCRIPTION
SIEMENS 7ML5221-1DA11 - Radar Level Transmitter
The SIEMENS 7ML5221-1DA11 is a SITRANS LR250 series 2-wire, loop-powered pulse radar level transmitter engineered for continuous, non-contact level measurement of liquids and slurries in industrial process applications. It employs 25 GHz K-band radar technology with a horn antenna and provides a 4-20 mA output with HART communication, facilitating integration into Distributed Control Systems (DCS), Programmable Logic Controllers (PLC), and SCADA systems for accurate process control and inventory management. This device is suitable for storage tanks, process vessels, and buffer tanks across various industries.
