Among the various technical parameters of pressure sensors, accuracy is an important indicator. In the industrial field, the accuracy of the instrument is called precision, and the level of accuracy is Xi called the accuracy level. The accuracy level of industrial instruments in China is divided into seven grades: 0.1, 0.2, 0.5, 1.0, 1.5, 2.5 and 5.0. The details are as follows: 1% FS = Class 1 Measurement error is less than or equal to one hundredth of full scale 0.5%FS = 0.5 The measurement error is less than or equal to 5/1000 of full scale 0.25%FS = class 0.25 The measurement error is less than or equal to 2.5 thousandths of full scale 0.1%FS=0.1 class The measurement error is less than or equal to 1/1000 of full scale The higher the accuracy of the pressure sensor, the more expensive it is, and many customers do not understand the accuracy of the pressure sensor from a professional point of view in the selection of pressure sensor. In fact, the accuracy of the pressure sensor only needs to meet the accuracy requirements of the entire measurement system, and it does not have to be too high. The accuracy of a pressure sensor can also be affected by many factors. With the development of science and technology, the application of pressure sensors in daily life production is becoming more and more abundant and the scope is becoming more and more extensive. However, as a kind of instrumentation, the measurement accuracy of the pressure sensor is the most basic requirement.
