Siemens SITRANS LR120 Series Radar Level Transmitter Level Sensor, NO-Rated

This transmitter is a radar level device designed for continuous level measurement in industrial settings. It operates reliably at low ambient temperatures and connects via a fixed cable, making it suitable for remote installations and integration into control systems. Certifications cover multiple regional standards for safety and installation compatibility.

• Operates down to -40°C for low-temperature environments
• Supplied with a 10 m cable for extended mounting distance
• Two-wire design for simple loop-powered wiring
• Radar technology suitable for liquids and solids measurement

• Suitable for bulk liquid storage monitoring in process plants
• Ideal for level control in chemical and petrochemical vessels
• Used for solids inventory measurement in bulk-handling systems
• Can be used with remote PLCs and DCS via loop connection

It uses a two-wire loop arrangement, supplying power and signal over the same pair to simplify cabling and reduce field-wiring complexity.

The transmitter provides an industry-standard output compatible with common control systems, allowing direct connection to PLCs and DCS inputs that accept loop-powered sensors.

The device is specified to operate at temperatures as low as -40°C, enabling deployment in sub-zero climates without auxiliary heating.
