Abstract
The invention relates to a measurement transducer by which an electric measuring signal unambiguously associated with the angle between the direction of a homogeneous magnetic direct current field and a reference direction can be produced over the full measurement range of 360 DEG . The measurement transducer contains an annular core (2) of low-retentivity material, which is subjected to the homogeneous magnetic direct current field and carries three windings (6, 7, 8) to which a single-phase energising alternating voltage is applied. A resistor (10, 11, 12) is connected in series with each of the windings (6, 7, 8). The other supply lines (16, 17, 18) of the windings are electrically connected together at a common connection point (19), and the supply lines (20, 21, 22) of the resistors are also electrically connected together at a common connecting point (23). Between the respective connecting lines (13, 14, 15) connecting each winding to a resistor, output voltages are tapped off as the electric measuring signal. The resistors may be replaced by input windings of a transformer, said output voltages being tapped from the output windings thereof. <IMAGE>
