EchoBeam® LR83 80-GHz Radar Liquid and Solids Level Sensor Transmitter
08203-HW-Flow-0203
Overview
The EchoBeam® LR83 is a reliable and easy-to-use non-contact level sensor transmitter utilizing advanced 80-GHz radar technology. Unaffected by most media, process, or environmental conditions, it delivers accurate, continuous level measurement for demanding industrial applications. Configuration is simple using the LevelTap™ App, LCD display, HART, or Modbus communication.

The LR83 is available in general-purpose or intrinsically safe models and provides continuous level measurement up to 98.4 ft (30 m) for liquids and 49.2 ft (15 m) for solids. It outputs a 4–20 mA signal with HART or Modbus protocol. Wireless Bluetooth configuration via the LevelTap™ App allows users to monitor level, verify status, and adjust settings safely from ground level or nearby access points.
