Abstract

1,124,576. Measuring magnetic fields. RELIANCE ELECTRIC & ENG. CO. Jan. 6, 1966, No.694/66. Heading G1N. [Also in Division G3] A Hall generator 10 for measuring a magnetic field is provided with an adjustable excitation current supply 18, Hall voltage output leads 26 and a calibration coil 32 supplied from a signal generator 36. The Hall voltage ouput signal Eh contains a component fk representative of the magnetic field produced by the coil 32 and a component fs representative of the magnetic field to be measured. The component fk is isolated by a filter 42 and from it is produced a direct voltage Ek which is compared by means of a chopper 54 with a standard voltage E std, any error signal being applied to control a servomotor 5 which operates in association with the source 18 to adjust the excitation current in a sense to reduce the error to zero. Thus the excitation current is automatically varied to correct for variations in the Hall effect voltage caused by changes in an ambient condition such as temperature, so that the signal fs, which is applied to a suitable analysing circuit 40 over a low pass filter 38 is rendered independent of such changes, and the relationship between a given change in magnetic field and the resultant change in Hall voltage is maintained constant. The comparator and regulating circuit may take different forms and three modified circuits are described with reference to Figs. 2, 4 and 6 (not shown).
