It is used to calculate the change in a measurement signal over time and thus represents the mathematical derivative of a source channel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While one measurement channel records the current value of a measured variable, the differentiator channel calculates how quickly that value changes over a specific time period. The result is displayed as <strong>Change per unit of time<\/strong> is displayed and enables a detailed analysis of dynamic processes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The calculation is performed continuously based on a selected source channel. This allows trends, accelerations, or rapid signal changes to be detected and analyzed early on, without the need for additional external calculations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In measurement, testing, and automation technology, differentiation is frequently used to determine the rates of change of physical quantities. For example, velocity can be calculated from a displacement measurement, or the rate of temperature change can be calculated from a temperature measurement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Typical examples of use:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Calculating Velocity from Distance or Position Measurements<\/li>\n\n\n\n<li>Calculating Acceleration from Velocity Values<\/li>\n\n\n\n<li>Analysis of Pressure Changes in Hydraulic or Pneumatic Systems<\/li>\n\n\n\n<li>Monitoring of temperature rise or cooling rates<\/li>\n\n\n\n<li>Detection of Rapid Process Changes in Test Benches<\/li>\n\n\n\n<li>Condition Monitoring of Machinery and Equipment<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Advantages of the differentiator channel:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Automatic Calculation of the Change in the Signal Over Time<\/li>\n\n\n\n<li>Real-time analysis directly within the measurement system<\/li>\n\n\n\n<li>No additional external signal processing is required<\/li>\n\n\n\n<li>Early Detection of Dynamic Process States<\/li>\n\n\n\n<li>Flexible integration with other virtual channels and features<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">As part of the Virtual Channels, the Differentiator Channel expands the capabilities of the Delphin measuring instruments by enabling powerful mathematical evaluations directly during data acquisition. This allows complex measurement tasks to be carried out efficiently and important process information to be made available immediately.<\/p>","protected":false},"featured_media":0,"template":"","class_list":["post-6776","glossar","type-glossar","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/glossar\/6776","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=6776"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
