Procedure for correcting the influence of the temperature on the measurements of a pressure transducer. |
摘要 |
<p>The invention relates to a procedure for correcting the influence of temperature transience on the measurements of a pressure gauge. There is added to the value of pressure measured at a time t a correction term A0.[T(t + tau ) - T(t)] proportional to the difference between the temperature T(t + tau ) measured after an interval of duration tau has elapsed starting from the time t, and the temperature T(t) at the time t. Application to measurements in oil drilling. <IMAGE></p> |
