Abstract
The invention relates to a system for remotely interrogating sensor units for machine monitoring, comprising a measuring device and a plurality of sensor units which are connected in parallel with one another and are connected to the measuring device via a common line in order to transmit sensor measurement signals as an analog signal from the sensor unit to the measuring device and in order to receive a digital query signal from the measuring device, wherein the control unit operates the switch depending on the digital query signal in order to switch the analog measurement signal onto the line, wherein, at each time, only at most one of the sensor units can switch its analog measurement signal onto the line, and wherein the analog measurement signal is in the form of a current signal and the digital query signal is in the form of a voltage signal.
