Claim Text:
1. A fill level measurement device to determine a fill level of a medium in a container comprising: a control unit, a spatially separated probe and a multicore connection line configured to connect the control unit with the spatially separated probe, wherein the control unit contains a high frequency generator configured to generate a transmission signal, an evaluation unit configured to evaluate by means of a first amplifier and a second amplifier amplified probe signals, wherein the spatially separated probe contains a measuring impedance, not from the medium influencable reference impedance for calibration and temperature compensation, a first rectifier and a second rectifier, wherein the multicore connection line is configured to apply to the spatially separated probe the transmission signal and further configured to transmit the probe signals to the control unit, wherein the first amplifier and the second amplifier are connected on the output side to the evaluation unit and are configured to amplify direct voltages transmitted via the multicore connection line to the control unit, wherein the first rectifier is configured to acquire a voltage of the transmission signal in the spatially separated probe; the first rectifier, in combination with capacitors and resistors, is configured to transmit a first direct voltage signal via the multicore connection line to the control unit, wherein the second rectifier breaks the probe current down into its two half-waves so that a first of the two half-waves is present across a first measurement resistor and a second of the two half-waves is present across a second measurement resistor, wherein a second direct voltage, transmitted by the second rectifier in combination with capacitors and resistors, is supplied via the multicore connection line to the control unit, wherein the first rectifier and the second rectifier are thermally coupled with each other.
