What distance range and accuracy does it offer?

0.3–50 m measuring range (customizable) with ±1 mm accuracy and 1 mm resolution — suitable for level-by-distance and displacement monitoring.

Does dust or humidity affect the measurement?

The radar-based measurement is designed for strong anti-interference in dusty, humid sites such as coal bunkers and manholes; the IP68 enclosure protects the device itself.

Can the range be extended beyond 50 m?

Yes, range and mounting are customizable. Tell Hitelecom your target distance and medium for a configuration proposal.

H Series · Radar Distance Sensor

Low Power | Precision | Millimeter-Level

The Hitelecom H Series ranging sensor is a wireless radar distance sensor with millimeter-level precision.
