Paper Title:
The Design of Closed-Loop Digital Fluxgate Sensor
  Abstract

In term of the problems that the traditional fluxgate sensors with analog circuit have low temperature adjust ability, the paper does research on closed-loop fluxgate sensors. It takes advantage of high speed AD signal collecting sensor, disposes the signals by single chip, and outputs analog signals by DA chips. It describes the hardware environment and software design, and tests the magnetic field by the new sensor. The results show that: its original temperature coefficient is 6.7×10-10/°C, sensitive temperature coefficient is 2.5×10-4/°C and its linearity comes to 5.4×10-3.
