FIELD: physics. ^ SUBSTANCE: magnetic transducer 10 includes ""-elements 11-18 and heatercoils 21-24 used as fuel elements. Elements 11-14 and 15-18 are bridge-wise interconnected making sensors of axis X and axis Y, respectively. Heater coils 21, 22, 23 and 24 are positioned next to the elements 11 and 12, elements 13 and 14, elements 15 and 16, and elements 17 and 18, respectively. Heater coils 21-24 at electric excitation heat up mainly the next elements. Data for compensation of temperature dependent characteristic (ratio of transducer output value variation to element temperature variation) is received on the basis of element temperatures before and after heating and output values of magnetic transducer before and after heating. Then element temperature characteristics are compensated on the basis of these data. ^ EFFECT: elements can be heated up and cooled during the short time period while maintaining constant geomagnetism. ^ 2 cl, 18 dwg |
