摘　　要：针对工业和科研领域常用的小量程微差压传感器,设计了一种简单实用的水头标定方案,给出了标定步骤。应用该方案标定国产某型号传感器,结果表明线性误差小于0.22%,完全满足应用要求。Designed a simple and practical calibrating method for micro silicon differential pressure sensor which is used widely in industry and scientific research field. Steps of calibrating are listed distinctly. One type of Chinese-made micro silicon differential pressure sensor was calibrated with this method. The calibrating result of linear error is less than 0.22% .The result indicates that water pressure calibrating method is suitable for silicon differential pressure sensor and has application value.
