It is one of the most important parameters for evaluating measuring instruments, sensors, and measurement systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In accordance with the metrology standard <strong>DIN 1319-2<\/strong> Accuracy is the degree to which a measurement result approximates the true value of the input quantity. The smaller the deviation between the measured value and the actual value, the more accurate the measurement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, however, the true value of a physical quantity usually cannot be determined directly. Instead, highly accurate reference systems and calibration standards are used. The value determined using these references is considered a sufficiently accurate approximation and serves as a benchmark for assessing measurement accuracy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Accuracy Classes of Measuring Instruments<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Many measuring instruments are used in so-called <strong>Accuracy Classes<\/strong> classified. These specify the permissible error limits within which a measuring instrument operates. The higher the accuracy of a measuring system, the smaller the possible measurement deviations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Actual measurement accuracy is influenced by various factors, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sensor Specifications<\/li>\n\n\n\n<li>Signal Processing Quality<\/li>\n\n\n\n<li>Resolution of the measurement system<\/li>\n\n\n\n<li>Temperature and Environmental Factors<\/li>\n\n\n\n<li>Calibration Status of the Device<\/li>\n\n\n\n<li>Measurement Range and Operating Conditions<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Accuracy in Industrial Measurement Technology<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In modern measurement, testing, and automation systems, high accuracy is crucial for reliable results. It forms the basis for quality control, process monitoring, research, development, and safety-critical applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Especially when measuring temperature, pressure, force, voltage, current, or vibrations, even small measurement deviations can have a significant impact on the evaluation of processes or products.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Accuracy, precision, and resolution\u2014they're not the same thing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The terms \"accuracy,\" \"precision,\" and \"resolution\" are often confused, but they describe different characteristics:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Accuracy<\/strong> describes how close it is to the actual value.<\/li>\n\n\n\n<li><strong>Precision<\/strong> describes the repeatability of measurement results.<\/li>\n\n\n\n<li><strong>Resolution<\/strong> describes the smallest detectable change in a measured value.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a measuring device can have high resolution without being particularly accurate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Benefits of High Measurement Accuracy<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Reliable measurement results<\/li>\n\n\n\n<li>Improved Process Control<\/li>\n\n\n\n<li>Higher product quality<\/li>\n\n\n\n<li>Early Error Detection<\/li>\n\n\n\n<li>Comparable and reproducible measurements<\/li>\n\n\n\n<li>Ensuring Compliance with Standards and Specifications<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Accuracy is therefore a key parameter in measurement technology and plays a decisive role in determining how meaningful and reliable measurement results are in industry, research, and development.<\/p>","protected":false},"featured_media":0,"template":"","class_list":["post-7329","glossar","type-glossar","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/glossar\/7329","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/glossar"}],"about":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/types\/glossar"}],"wp:attachment":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/media?parent=7329"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
