Overview

The 80G Ultra-High Frequency Radar Level Meter operates in the 76-81GHz range using Frequency Modulated Continuous Wave (FMCW) radar technology, supporting both four-wire and two-wire applications. It is available in various specifications, with a maximum range of up to 120 meters and a minimal blind spot of just 5 cm. Due to its higher operating frequency and shorter wavelength, it is particularly suitable for solid applications. The device operates by transmitting and receiving electromagnetic waves through a lens, offering advantages in high dust and extreme temperature environments (up to +200°C). It is ideal for water treatment industries, storage tanks for acids, bases, and additives in various industrial sectors, or for measuring levels through plastic container walls. The instrument can be easily installed using either flanged or threaded connections.

Main Technical Specifications

Working Principle

The 80G Radar Level Meter employs Frequency Modulated Continuous Wave (FMCW) technology. The antenna emits a high-frequency, frequency-modulated radar signal, with the frequency of the radar signal increasing linearly. The transmitted radar signal, after being reflected by the medium, is received by the same antenna. At the same moment, the frequency difference between the transmitted and received signals is directly proportional to the distance measured. The frequency difference signal is processed using Fast Fourier Transform (FFT) to obtain the spectrum of the reflected echo, which is then used to calculate the distance to the target object.

Features

High measurement accuracy up to ±1mm, with a minimum blind zone of 0.05m
Smaller antenna size, suitable for a wider range of operational conditions
Various lens antennas provide a smaller emission angle and more concentrated energy, resulting in stronger echo signals and higher reliability under similar conditions compared to other radar products
Enhanced penetration capabilities allow for normal operation even in the presence of adhesion and condensation
Larger dynamic signal range, providing more stable measurements for media with low dielectric constants
