摘要
国内传感器的标校工作未能正确、规范地进行 ,标校分析的不严谨 ,是造成严重误差的主要原因之一。对井下压力 /温度传感器的标校 ,建立一种传感器的数学模型。在此基础上 ,应用多元回归分析方法 ,获得一种良好的校验公式 。
The calibrations of sensors have not been made correctly and standardly at home.But rigorouslessness of calibration analysis is the major factor to cause serious error.The oil reservoir pressure/temperature sensors are calibrated and a kind of mathematical simulation is established.A demarcating formula of the sensor is obtained by using multiple regression analysis,which provides the basis for the measurement of high precision.
