LSR-801 Radar Level Sensor

24VDC Power, Simple Radar Level Measurement.

Monitor for liquid level up to 591 inches (49.2ft / 15m) with this simple to operate Radar Level Sensor.

CE Mark



The LSR-801 sensor is a W-band FMCW continuous frequency modulation radar level transmitters. They provide continuous level measurement up to 591 inches (49.2 ft. or 15m) with 4-20 mA output as well as RS485, BlueTooth 5.0®.

The LSR-801 Series can be wirelessly configured via the uPyxis® app for Mobile or Desktop devices. This enables rapid integration and deployment in the field. The sensors are powered by a 24 VDC external power supply. This makes them ideal commonly used OEM controllers, PLC or DCS systems. This non-contact liquid level sensor platform is well suited for corrosive liquids. As well as industrial, municipal, process liquid storage and chemical feed applications.
