Abstract

PURPOSE:To increase the measuring accuracy, by adding an amorphous metallic soft magnetic matter into a magnetic circuit of a detection coil and then applying the bias having a magnetic field adverse to the magnetic field produced by the detection coil. CONSTITUTION:For a temperature sensor 1, an end of a bimetal 3 is held in a casing 2 with a resin filler 4, and a detection coil 7 and a bias coil 8 are wound around a bobbin 6 provided between the end face of the filler 4 and the stage part of the casing 2. Then an amorphous metallic soft magnetic matter 11 which is in a magnetic circuit formed with the coils 7 and 8 is joined to the bimetal 3 which hangs down via the bobbin 6. If the ambient temperature increases to bend the bimetal 3 to the right side of the diagram and then to cause a tensile force to the matter 11, the magnetic permeability also increases in proportion to the increase of the ambient temperature. As a result, the time during which the voltage is applied to the coils 7 and 8 and then the current of the coil 7 reaches a prescribed level is increased in accordance with the stress. This time is measured in the form of the biased value. Thus the output and the measuring accuracy can be increased.
