JFR3 FMCW radar level transmitter is a non-contact measuring device, suitable for liquid level measurement in most tanks. It is easy to install, convenient to maintain, and can be used in corrosive applications. With its high precision and stability, it is widely used in liquid level detection and process control in the industrial field. FMCW radar (JFR) adopts a high frequency (GHz level) scanning method; electromagnetic waves are transmitted from the antenna to the target to be measured, then reflected to the receiver over time. During this period, a frequency difference will appear, which can be further calculated to obtain the distance from the transmitting end to the measured object. FineTek FMCW radar uses K Band frequency scanning, with a measurement bandwidth of around 1 GHz. The frequency difference is processed by Fast Fourier Transformation (FFT) which can accurately distinguish the main signal from background noise or echoes. Using a phase-lock Loop (PLL) circuit will result in a high accuracy and reliable measurement.
