Radar Level Measurement

80GHz millimeter wave radar electronic module used in non-contacting radar level transmitter for liquids and solids

The 80GHz millimeter-wave radar module is a key part used in non-contact level transmitters to measure liquids and solids with high precision. It works well even in demanding environments like steam, agitation, or dusty conditions. Thanks to its compact design and compatibility with different antenna types, it can be installed in threaded, corrosion-resistant, sanitary, or high-temperature setups, reaching up to 1000°C when needed.

Features

Uses a self-developed radar chip that gives very precise readings, up to ±1 mm, and keeps the blind zone as small as 2 cm for more accurate measurements.
Supports Bluetooth connection and remote setup, so the system can be adjusted or maintained easily without being on-site
Multi-language interface available, with customizable display options.
No distance calibration required, simplifying assembly and production
