HCDAR-8x series radar level sensor is one kind of level measuring instrument which uses FMCW special millimeter wave technology, the working frequency is 76-81GHz.
The signal output has options: 2-wire 4-20mA, 4-wire 4-20mA or RS485.
The max measuring range can reach 120m, and the blind zone of 8cm.
The antenna beam angle is about 3°, the outstanding performance makes it workable for the accurate measurement of liquids, solids and powder materials.

HCDAR-8x series launch a microwave signal frequency changing with the time linearly, the reflected signal and the launched signal are mixed through the “mixer”.
The difference of frequency is proportional to the distance from radar to the reflection surface and get the distance information required through the FFT transform.

HCDAR-6x series has small beam angles, and strong anti-interference ability, which improves measurement accuracy and reliability.

The antenna size is smaller, easy to install. It has small measuring blind zone and shorter wavelength.

HCDAR-6X has a good measurement effect for small tanks and small particles. Non-contact measurement, no wear, no pollution.

Output option: 2-wire (4-20 )mA HART and 4-wire RS485 Modbus.
