HJ11867 is a signal processing circuit for fluxgate sensors. This circuit includes a half-bridge excitation source circuit, three signal measurement circuits, a bias voltage source, and a temperature sensor, among others. The three signal measurement circuits consist of selective frequency amplification, phase-sensitive detection, integration links, force feedback links, and bias circuits. The environmental magnetic induction intensity is measured using the second harmonic method. The HJ11867 fluxgate signal processing circuit has advantages such as high detection accuracy, high reliability, good stability, high-temperature resistance, and ease of debugging. It can be widely used in magnetic compasses, while drilling inclination measurements, open-hole well inclination measurements, and rotary steering applications when paired with various types of fluxgate sensors.
