JWrada-31 Radar Level Meter
The JWrada-31 radar level meter uses 80GHz FMCW radar technology with an integrated antenna, offering a maximum measurement range of 120 meters. It operates on a non-contact principle, providing high precision and excellent signal-to-noise ratio. Easy to use and maintenance-free, it remains unaffected by medium variations or process conditions. Widely used in reactors and storage tanks, the JWrada-31 ensures stable, accurate measurements even in harsh conditions like steam, pressure, and dust.
The JWrada-31 is an 80GHz FMCW radar level transmitter featuring an integrated antenna design and a maximum measuring range of up to 30 meters. It offers non-contact, high-precision measurement with a high signal-to-noise ratio, simple operation, and maintenance-free performance. Its measurement is unaffected by changes in medium properties or challenging process conditions such as steam, pressure, or dust, making it ideal for use in reactors and storage tanks.
Equipped with Bluetooth connectivity, the JWrada-31 allows for wireless configuration and data access via the Jiwei Smart Control mini-program. It also features an innovative echo learning and self-adaptive algorithm that intelligently identifies valid echoes and automatically adjusts to changing conditions, ensuring stable and reliable level measurement.
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.
