Accuracy of pressure sensors | Keep an eye on those 3 errors!

What does accuracy actually mean with pressure sensors and how do inaccuracies, as in deviations from the desired measuring result, come about? In the video we explain the most important factors relevant for accuracy for pressure sensors: the zero point error, the span error and the non-linearity. The latter describes the greatest possible deviation of the characteristic curve from a reference straight line. There are different methods to determine the reference straight line. The two most common are the terminal method and the best-fit straight line method (often called BFSL in data sheets). If one compares both methods with each other, the terminal method usually provides a deviation that is twice as large as the best-fit straight line method. A comparison of the non-linearity of electronic pressure measuring instruments from different manufacturers is, therefore, only representative provided the non-linearity is determined using the same method.

The interplay of zero point error, span error, non-linearity and other errors − such as hysteresis and non-repeatability − is colloquially referred to as “accuracy”. The term “accuracy” only exists in the user's dictionary. It is not defined in any standard. Nevertheless, it can be found in many of the data sheets for sensors. Unfortunately, there is no common understanding of what accuracy means. There isn't actually “accuracy”, but rather a variety of data relevant to accuracy. All of them together describe the “accuracy” of an instrument. The factors relevant to the accuracy for pressure sensors are uniformly defined across standards. Nevertheless, the manufacturer's information cannot really be compared with each other, since which accuracy specifications and how they are specified in the data sheet is a matter for each manufacturer. An example of this: Accuracy figures are determined statistically, since measuring errors contain both a systematic and a random element. It is necessary to distinguish between the measuring errors specified as “maximum” and “typical”. For a maximum error, it is expected that no single instrument has a greater error than that specified. In fact, the majority of the delivered products should actually have a considerably smaller error. If an error is given with the description “typ.”, which stands for typical, it is to be expected that not every single instrument complies with this accuracy data. In the extreme case, this may mean that an individual instrument has a measuring error several times the specified “typical” error.
