摘要：PURPOSE:To obtain a detector facilitating the adjustment of outputs with limited number of parts, by providing an adjusting resistance allowed to be trimmed from outside through a notch arranged on a ca of a circuit board with magneto-nsitive elements mounted thereon. CONSTITUTION:Becau of variations in magnetic characteristic of a ferromagnetic core 1, dimensions of a magnetic gap 2, characteristics of a magneto- nsitive element 3 and a differential amplifier and the like, a detector unavoidably varies in the output signal. To hold the variations in the output signal within a desired range, a part of a signal processing circuit is provided with an adjusting resistance 13 and a fixed current to be measured flows through a coil 5 to trim the resistance 13 obrving an output voltage so that the resistance value is changed to reduce the variations. In this manner, the mounting of the magneto-nsitive element 3 on a circuit board 8 eliminates a lead for connecting both the parts and no additional adjusting resistance is required thereby reducing the number of parts. This also facilitates the trimming through the notch 12 to assure a stable output regardless changes in the environment.
