摘要
改进压力传感器拟合特性的温度补偿算法陆庭恕,江潼君,钱侬仙(东南大学电气工程系,南京210018)深井高精度电子压力计是一种用于采集井底压力、温度数据,以便对油气储量作出分析评价的重要设备,这种压力计的压力传感器将井底压力和温度分别变换成频率信号,再...
An algorithm of fitting characteristic for pressure gauge used in deep weel is presented.Onthe basis of general polynomial expression fitting of the V-F characterlstic, a group of coefficients oftemperature componsation is given. The algorithin can obviously increase the precision of measure-ment, and shorten the time for calibration,The calculation formu lae of the compensation coefficientsand a practical example are given.
