G80 is the latest product of the 5100 series, which is different from other radar level transmitters in the 5100 series. The G80 frequency can reach 80 GHz. The instrument emits a continuous radar signal through its lens antenna. The frequency of this signal will change like a sawtooth. The transmitted signal is reflected by the medium and received by the antenna as an echo signal. There is always a frequency difference between the received signal frequency and the current transmission frequency. The frequency difference is directly proportional to the material level in the container, and the accurate value of the level is calculated through a specific algorithm of the sensor. The G80 series operates with very low transmission power in the W-band range.
