【Abstract】 Based on proper calibrating methods and its standard linear output behavior, diffusion silicon pressure sensor was used as a pressure-detecting component in the process control system of water-power model experiment equipment by an interface circuit. The measurement precision was improved by reducing measuring error of range movement in the design. Additionally, multi-point integrated and digital network measuring and controlling would conveniently be realized based on the design for its standard output.更多还原
