Sensor interface with a current measurement unit which is integrated

The present invention is a drive control evaluation device for different sensor units, the energy supply unit electrical energy is stabilized to be supplied to the sensor unit, the input signal to the generated amplifier arrangement by the sensor unit It has an amplification of the sensor signals supplied, an amplifier device for outputting the measurement signal depending on the sensor signal, and an output unit for outputting a measurement signal as an output signal as a. According to the present invention, the integrated measuring resistor in the amplifier device is provided for measuring the voltage drop caused by the sensor signal, the voltage drop is fed to the amplifier arrangement as the input signal is provided to a downstream-connected comparator unit compares the measurement signal with a predetermined threshold value to the amplifier device, the threshold value can be set depending on the sensor unit to be used.
