FMCW radar level sensor USR30

for solidsfor liquidsdigital output

Product description
The USR30 is the smallest form factor of the new radar sensors designed for custom OEM applications. It provides the full functionality of the UTR30 without housing and without a defined electrical connector. The sensor outputs a digital signal (UART) that can be processed and integrated into application-specific systems. The module can be configured to match the target medium and measurement conditions.

Advantages

• Precise distance measurement using Time-of-Flight (ToF): continuous, non-contact measurement up to 35 m for tanks and silos, and level measurement in open water.
• Flexible parameterization: adapt settings for medium (solid/liquid), empty/full thresholds, blind-zone distance and sensitivity (low/medium/high) to suit customer applications.

Technology

• Time-of-Flight (ToF) measurement principle
• Radar FMCW, 80 GHz

Safety and compliance

• Compliant with ETSI EN 302 729
• Open-field radio approvals at component level (FCC, ISED)
• RoHS and REACH compliant
