Sensor accuracy is one of the important indicators to measure the quality of the instrument, and many customers do not understand the sensor accuracy from a professional perspective in the selection of sensors. The sensor accuracy includes zero drift, full-degree drift, temperature drift, time drift, linearity, repeatability, measurement accuracy and other parameters. How is sensor accuracy defined? Meter accuracy is customarily referred to as accuracy, and accuracy classes are traditionally referred to as accuracy grades. China’s industrial instrument grades are divided into: 0.1, 0.2, 0.5, 1.0, 1.5, 2.5, 5.0 seven grades, and marked on the instrument scale or nameplate. 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. Sensor accuracy is an important performance index of the sensor, which is related to an important part of the measurement accuracy of the whole measurement system. The higher the accuracy of the sensor, the more expensive it is, so the accuracy of the sensor only needs to meet the accuracy requirements of the entire measurement system, and it is not necessary to choose too high. This makes it possible to choose between a number of sensors that meet the same measurement purpose that are relatively inexpensive and simple. Sensor accuracy can also be affected by many factors. High temperature environment, corrosive environment, dust, humid environment, flammable, explosive environment, etc. With the development of science and technology, the application of 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 sensor is the most basic requirement.
