ABSTRACT:
A two-wire type current output sensor includes two external connection terminals to one of which a power supply flows from an outside and from the other one of which the power supply flows to the outside, a detecting element capable of outputting a detection signal, a signal processing circuit for changing a current supplied to a power supply side of the signal processing circuit based on the detection signal of the detecting element and outputting the changed current, and a connection switching circuit for switching a connection between the two external connection terminals and the signal processing circuit such that one of the external connection terminals at a higher voltage is connected to the power supply side of the signal processing circuit while the other one of the external connection terminals at a lower voltage is connected to an output side of the signal processing circuit.
