FMCW radar level sensor UTR30

for solidsfor liquidsdigital output

Overview
The UTR30 radar module provides continuous, non-contact level and distance measurement for tanks, silos and open-water applications. Measurement is based on the Time-of-Flight (ToF) principle and is suitable for ranges up to 35 m. The module is available as a bare sensor or as a customer-configured unit with defined electrical and process interfaces.

Benefits

• Accurate ToF measurement
  Continuous, contactless measurement using time-of-flight enables precise distance readings up to 35 m. Radar operation remains reliable under movement, rapid temperature changes and harsh environmental conditions.
• Flexible parameterization
  Sensor parameters can be adapted to application needs. Configure medium type (solid/liquid), sensitivity (low/medium/high), empty/full thresholds and block distance.
• Application-specific configuration
  Housing, electrical connection, process connection and communication interfaces can be customized to project requirements.
