  • Signal transmission device for a measuring probe, as well as transmission method and measuring probe
    Patent number: 7683803
    Abstract: A signal transmission device is disclosed, which serves to connect a measuring probe, in particular a pH measuring probe or an oxygen measuring probe, to a signal-processing unit. The signal transmission device includes a differential amplifier at whose non-inverting input an input signal can be applied which is provided by an electrode of the measuring probe, and from which a corresponding low-impedance output signal can be delivered to a transmission line, by which the output signal can be transmitted to the signal-processing unit. The output of the differential amplifier can be connected via a first resistor to the transmission line and to the inverting input of the differential amplifier, and can be connected to the input of a first control unit by which signals can be registered, such as clock signals and/or data, which are applied to the transmission line by the signal-processing unit.
