Magnetic sensor and position transducer

摘要

A position transducer includes a bias circuit 46 which drives and controls first and second bias coils 27a and 27b. The bias circuit 46 monitors the value of a voltage produced in a second sensor coil 29b, and drives and controls the first and second bias coils 27a and 27b for the value of the voltage produced in the second sensor coil 29b to always be equal to a desired voltage value.
