Design and Implementation of High-Precision Mine-Used Water-Pressure Sensor

Abstract:

A novel mine-used water-pressure sensor is presented in this paper, the configuration, working principle and design of main circuits are introduced in detail. Using pressure sensor, high precision 24 bits A/D converter AD7714 and low power consumption MCU P89LPC932 to complete the water-pressure measurement, and transferred the measuring results to upper computer through M-BUS, realized the stability measurement of high precision and low power consumption.
