Its purpose is to generate a unique pulse per revolution, which is used to determine the <strong>Speed<\/strong>, <strong>Direction of rotation<\/strong> and, in particular, the <strong>Phase angle<\/strong> can be precisely determined for rotating machines.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Keyphasor signals play a central role in vibration analysis, condition monitoring, and the diagnosis of turbines, pumps, motors, generators, and other rotating machines.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Importance of the Keyphasor in Measurement Technology<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In industrial measurement technology, a keyphasor enables the synchronous acquisition of vibration, acceleration, or displacement signals relative to the exact rotor position. This allows measurement data to be assigned to a specific angular position and enables the reliable detection of faults such as imbalance, shaft misalignment, looseness, or bearing damage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Typical applications are<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>RPM Measurement<\/li>\n\n\n\n<li>Phase Measurement<\/li>\n\n\n\n<li>Order Tracking<\/li>\n\n\n\n<li>Vibration Monitoring<\/li>\n\n\n\n<li>Rotor Dynamics Studies<\/li>\n\n\n\n<li>Machine and Equipment Monitoring<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Thanks to the unique reference per revolution, even the slightest changes in a machine's operating behavior can be detected early on.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Keyphasor Measurements Using Delphin Measurement Technology<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>Measurement data acquisition systems<\/strong> Delphin's solutions enable the precise acquisition of keyphasor and speed signals, as well as their synchronization with other measured variables such as vibration, temperature, pressure, or force. This allows complex measurement tasks to be efficiently carried out on test benches, test setups, or industrial plants.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In connection with the <a href=\"https:\/\/www.delphin.de\/en\/products\/measurement-software\/\">measurement software<\/a> The recorded signals can be visualized, analyzed, and documented. This results in meaningful evaluations for condition monitoring, fault diagnosis, and the optimization of rotating machinery.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Advantages of a Keyphasor<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The use of a keyphasor offers numerous advantages:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Meaningful measurement data for development, test bench, and maintenance<\/li>\n\n\n\n<li>Precise Reference for Rotating Systems<\/li>\n\n\n\n<li>Precise Determination of Speed and Phase Angle<\/li>\n\n\n\n<li>Basis for Order and Vibration Analyses<\/li>\n\n\n\n<li>Early Detection of Machine Malfunctions<\/li>\n\n\n\n<li>Higher System Availability Through Condition-Based Monitoring<\/li>\n<\/ul>","protected":false},"featured_media":0,"template":"","class_list":["post-7340","glossar","type-glossar","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/glossar\/7340","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=7340"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
