Abstract

A torqueshaft magnetic field measurement system includes a ceramic package enclosing a magnetoresistive sensor for converting a sensed magnetic field into a differential output voltage, an amplifier for converting the voltage into an amplified sensor signal, and a temperature sensor. An electrical cable connects the ceramic package to an electronic controller with a microprocessor.
