The JFR Series is a open-air radar level transmitter designed for measuring the changing level of liquids, slurries and bulk solids in tanks, bins and silos. Operating at either 10GHz or 26GHz the JRF series radar level transmitter products will provide non-contact continuous level measurement with high accuracy and reliability.
JFR Series FMCW Radar Level Transmitter
The JFR series is an open-air radar level transmitter product line designed for use measuring liquids and bulk solids in tanks, bins and silos. These radar level transmitters are designed to operate at either 10GHz or 26GHz and use FMCW (frequency modulated continuous wave) radar technology. An FMCW radar level transmitter emits a high frequency signal via an antenna towards the material surface. A part of the radar energy is reflected off the material surface back to the radar level transmitter at some time delay. The difference in frequency between the transmitted signal and received signal is directly related to the distance being measured by the radar level transmitter. This frequency difference is processed by the electronics As a result the linearity and accuracy of the measurement made by the JFR radar level transmitter is excellent, with an error rate as low as only ± 0.197″ (5mm).
