We usually use pressure sensor is mainly based on the piezoelectric effect and make out. How about the performance of pressure sensor is reasonable on the one hand for pressure sensor error compensation. Its error sources are mainly sensitivity error and offset error, linear error and hysteresis error (the content of the error can be found in the four: cn/favoanuluswesassapastle kehuxuyaozhuyiykickartefactpolisfch_1.

& have spent & have spent & have spent Due to the constant vertical migration in the whole pressure range, so the converter diffusion and amendments to the laser control changes will produce offset error. The size of the error sensitivity, it is proportional to the pressure. If the device sensitivity is higher than the typical values, error will be increasing function of pressure sensitivity, otherwise the opposite. In actual measurement, the hysteresis error generally up slightly, unless in place of pressure change is very severe. Linear error source is the nonlinear sensor sensitive device physics, if the amplifier is contained in the sensor, it also should include the non-linear error amplifier. Linear error curve may be concave, also may be convex.

Sensor calibration can eliminate or greatly reduce these errors, and compensation technology on UK Watson Wchangeorganisation imported sensor requirements determine the parameters of system transfer function is actual, rather than simply using typical values. Potentiometer, adjustable resistance, and other hardware can be used in the process of compensation, while the software can work more flexibly to realize the error compensation.
