Unlike a time diagram, it does not use time as the X-axis, but rather a second variable. This allows physical, electrical, or mechanical relationships to be directly visualized and analyzed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Typical characteristic curves include, for example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Current-Voltage Characteristic (I-V Curve) of a Diode<\/li>\n\n\n\n<li>Torque-Speed Curve of a Motor<\/li>\n\n\n\n<li>Pressure-Flow Characteristic Curve of a Pump<\/li>\n\n\n\n<li>Force-displacement curve in material or component testing<\/li>\n\n\n\n<li>Temperature-Resistance Characteristics of Sensors<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Performance charts are among the most important forms of visualization in industrial measurement technology, as they illustrate the behavior of components, machines, or entire systems under various operating conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Characteristic Curves in Measurement Technology<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In modern measurement and testing technology, characteristic curves are used to accurately evaluate a system's behavior. Instead of simply examining individual measurement points, entire relationships can be analyzed. This makes it possible, among other things, to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Characterize components<\/li>\n\n\n\n<li>Evaluate test benches<\/li>\n\n\n\n<li>Calibrate Sensors<\/li>\n\n\n\n<li>Determining Efficiency<\/li>\n\n\n\n<li>Examining Material Properties<\/li>\n\n\n\n<li>Document quality inspections<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Particularly in development, laboratory, and end-of-line testing, characteristic curve diagrams provide a much more meaningful analysis than individual measurement values.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Performance Charts with ProfiSignal<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Using the measurement software <strong>Pro<\/strong><a href=\"https:\/\/www.delphin.de\/en\/products\/measurement-software\/profisignal\/\" data-type=\"produkt\" data-id=\"2335\">ProfiSignal<\/a><strong>fiSignal<\/strong> With Delphin Technology, you can easily create and evaluate characteristic curves. Any measurement channels can be linked as the X and Y axes, allowing physical relationships to be visualized immediately. The software supports both online and offline analysis and offers numerous analysis functions such as zoom, cursor, statistics, and export options.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When used in conjunction with Delphin's measurement data acquisition systems, characteristic curves can be recorded and analyzed directly during the measurement. This enables efficient evaluation of test sequences, test series, or continuous process data.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Advantages of characteristic curves<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Performance charts offer numerous advantages for users in industry, research, and development:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Direct Representation of Physical Relationships<\/li>\n\n\n\n<li>Quick Assessment of System Behavior<\/li>\n\n\n\n<li>Support for Calibration and Testing Processes<\/li>\n\n\n\n<li>Comparison of Different Measurement Series<\/li>\n\n\n\n<li>Early detection of deviations or errors<\/li>\n\n\n\n<li>Comprehensive documentation for quality assurance and development<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">By combining high-performance measurement technology with intelligent visualization software, even complex measurement tasks can be efficiently analyzed and documented.<\/p>","protected":false},"featured_media":0,"template":"","class_list":["post-7339","glossar","type-glossar","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/glossar\/7339","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=7339"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
