Development of the displacement sensor on the basis of integral accelerometer for the dynamometer-dynamometer systems for deep well rod pumps

Article preview

Load indicator reading systems are commonly used to diagnose the condition of a downhole pump. Such systems consist of two sensor units: a force sensor and a displacement sensor. Currently, motion sensors based on integrated accelerometers are widely used. The use of accelerometers allows to create reliable, inexpensive, simple and convenient displacers. However, such sensors have a significant disadvantage, which is a large error due to the following reasons: a large integration error occurs in double integration; measured acceleration signals have a significant level of noise; currently produced integrated accelerometers have a large intrinsic error. In this paper, various methods are developed and investigated to solve these problems.
