摘要：
A system is disclosed for detecting an electrical sensor, the system includes a sensor signal processing circuit further comprising an input port to receive a connector including the output signal lines of the sensor, a resistor connected to the output signal line of said input port, wherein the resistor is connected to a predetermined voltage; a sensor circuit having a connector adapted to connect to the connector, wherein the sensor circuit has a resistance substantially less than the pull-resistor, and the sensor signal processing circuit detects an unconnected sensor based on the voltage applied by the resistor.
