The JW Rada-31 radar level meter is an 80 GHz FMCW (Frequency Modulated Continuous Wave) radar level meter with an integrated antenna structure, offering a maximum measuring range of up to 30 meters. The JWRada-31 is a non-contact measurement device, characterized by high accuracy, high signal-to-noise ratio, ease of operation, and maintenance-free performance. It is unaffected by changes in medium properties or process conditions, making it suitable for use in complex conditions such as reactors or tanks with steam, pressure, and dust.
The JWRada-31 radar level meter utilizes Frequency Modulated Continuous Wave (FMCW) technology. Its internal circuitry generates radar waves with a frequency of 80GHz, which are emitted through the antenna. When the emitted microwaves encounter the surface of the measured medium, they are reflected back and received by the same antenna. The frequency difference between the transmitted and received signals is directly proportional to the measured distance. The collected signal is processed using Fast Fourier Transform (FFT) to obtain the frequency spectrum of the reflected echo, thereby calculating the distance or level of the measured medium.
