摘要：
An induction meter based on a Hall-effect transducer with in-phase signal suppression and thermostabilization circuits is described. It is powered by a 103-Hz ac line. The maximum relative error in temperature measurements from 0 to 70°C does not exceed 0.7 % for magnetic fields of 50–100 μT, 0.4% for 0.1–1 mT, and 0.1% for 1–625 mT. In the range of 50–500 μT, the error is determined by an in-phase signal. The contribution of the total temperature error is ≤0.01% per 50°C. Depending on the induction of the measured magnetic field, the resolution changes from 0.12 to 19 μT.
