A DC bridge circuit 16 is formed from three impedance circuit elements including magnetic field generating coils 11, 12, and 13, respectively, and both output terminals 16a and 16b of the bridge circuit 16 are connected. The coils 11, 12, 13 are inserted between at least one side or both output terminals 16a, 16b of the bridge circuit 16, and the magnetic field by the coils 11, 12, 13 is applied to the sensor 15.
In the cross-coil type instrument, the cross-coil type instrument is formed so as to form at least a part of a cross-magnetic field whose synthetic magnetic field direction changes as the resistance value changes, and a movable magnet 30 is disposed under the action of the cross-magnetic field. A cross-coil type meter characterized by being provided with alarm circuits 20, 21, 22, and 23 that switch to an alarm mode upon detecting that the potential difference between both output terminals 16a and 16b of the circuit 16 reaches a predetermined value. (2) The alarm circuits 20, 21, 22, 23 are connected to both output terminals 16a, 16b of the bridge circuit 16.
The crossed coil type meter according to claim 1, characterized in that it is a light emitting diode 20 inserted between them.
