With a compact design, easy installation, and robust industrial housing, the HCDAR-85 radar level sensor is ideal for continuous monitoring of liquid levels in tanks, silos, reservoirs, and process vessels across a wide range of industrial applications.

A radar level sensor is an advanced industrial measurement device used to determine the level of liquids or solids in tanks and containers using electromagnetic radar waves.

Unlike traditional contact-based level measurement technologies such as float switches or capacitive sensors, radar level transmitters operate without direct contact with the measured medium. This ensures greater durability, higher measurement reliability, and reduced maintenance requirements.

Radar level measurement works by transmitting microwave signals toward the surface of the liquid. The signal reflects back to the sensor, and the system calculates the distance based on the time-of-flight of the radar wave.

Modern radar level sensors like the HCDAR-85 use FMCW (Frequency Modulated Continuous Wave) radar technology, which offers superior measurement accuracy and better signal processing compared to older pulse radar systems.

Key advantages of radar level measurement include:

  • Non-contact measurement

  • High accuracy and stability
