A sensor to measure dielectric constant of a medium may have a transmission line acting as a probe, and electronic circuit, and cable filter providing to reduce sensitivity of the sensor to cable parameters and influences. The sensor circuit may use a periodic signal generator to produce a carrier wave, which stimulates the transmission line, through a complex network coupling element. The complex impedance network forms a voltage divider with the transmission line, wherein the output of the v...
