Radar Level Transmitter – JFR Series
The JFR series FMCW radar level transmitter is a non contact measuring device, which is suitable for high temperature, high pressure, and corrosive applications. It is easy to install and free of maintenance, especially for the high accuracy requirement environment.
The JFR series FMCW radar adopts a high frequency signal, which is emitted via an antenna and swipe frequency increment by 0.5GHz during the measurement, reflected by the target surface and received at a time delay. The frequency difference, which is calculated from the transmitting frequency and the received frequency, which is directly proportional to the measured distance (or material surface). The frequency difference then is processed by Fast Fourier Transformation (FFT) to identify the signal in Intermedium Frequency (IF). This FMCW radar is innate with signal / noise enhancement and filtering of echo-back via Phase-Lock Loop (PLL) circuit that is the best solution for complex environment and high accuracy measurement.
