    Introduction

    Dynamic Direction Sensor

    Introduction
    ER-DOS-03 Dynamic Fluxgate Directional Assembly includes a three-axis high-temperature high-precision acceleration sensor and a three-axis high-temperature fluxgate sensor. The product uses a 24-bit high-resolution ADC to digitize the output signal of the sensor for temperature drift and quadrature compensation. The sensor can accurately measure well angle, tool face angle and azimuth angle within the range of 0~150℃.
    The product has the characteristics of small size, compact structure, strong anti-vibration ability, high reliability and excellent performance. The built-in digital filter and compensation algorithm can remove the interference signal of vibration and rotation, and accurately measure the vibration and rotation under the angle. In addition, the external size, installation method and digital output interface (UART or rs-232) of the probe can be customized according to different customer requirements.
