Abstract

PURPOSE: To miniaturize the power source of a sensor drive circuit and to make it a power-saving type by using a system for controlling a power source for driving the sensor so that it supplies a current only when data sampling is carried out.
CONSTITUTION: In a controller 19, when it needs that the data of a sensor 17 is sampled, a closing command signal is applied to a switching circuit 26 via a transmission circuit 24b of a control part 14, a phototransmitter 16c, and a receiving circuit 23b of a sensor part 13, and a driving power is supplied to an amplification computing circuit 25 and a transmission circuit 24. Furthermore, the detected data of a sensor 17 is taken into the controller via the amplification computing circuit 25, transmission circuit 24a, phototransmitter 16a and receiving circuit 23a, and data is supplied to the computing circuit 20, where the contents recorded in a set reference recording circuit 21 are compared with the data taken in, and computed, and the result is displayed in a display circuit 22.
