PROBLEM TO BE SOLVED: To provide a coil type wiring controller for flux gate type magnetic sensor elements that can more easily and reliably than by conventional practice cause magnetic sensor elements to operate continuously while maintaining comparable performance to that before disconnection of coil type wirings.SOLUTION: A coil type wiring controller is equipped with: a magnetic sensor element having two or more coil type wirings each wound around a magnetic core and electrically connected to one another in parallel; constant electric current supplying means that supplies a constant electric current to the two or more coil type wirings; constant voltage monitoring means that monitors the value of constant voltage generated between the coil type wirings by the constant current; and constant electric current adjusting instruction signal input means that determines whether or not the value of voltage acquired at any time on the basis of the result of monitoring by the constant voltage monitoring means is above the value of constant voltage and, if it is, generates an instruction signal to cause the constant electric current supplying means to so adjust the value of the constant current that the value of voltage and the value of constant voltage become substantially the same and to have the signal inputted to the constant electric current supplying means.SELECTED DRAWING: Figure 1 |
