People often use one per year or in case of very clean gas, one per 2 years. The following questions\/points can be helpful:<\/p>\n<ul>\n<li>How important is it to maintain the accuracy of the measuring device?<\/li>\n<li>What is the maximum allowable deviation?<\/li>\n<li>Can the user determine the deviation of the measuring devices himself by means of a reference?<br \/>\n<em>Prior to installation into the system, the actual state is detected by means of a reference device. The customer determines the periodic inspection himself. It is important to make sure thereby that the measuring setup is always the same.<\/em><\/li>\n<li>Internal or external specifications determine the interval:<br \/>\nIs a periodic calibration from an accredited body required (e.g. Dakks (previously DKD) or SCS)?<\/li>\n<li>Is the actual state determined prior to a recalibration?<br \/>\n<em>Yes, provided that the measuring device works, the current deviation is determined. A report is generated thereby. If it lies outside of the device specification, the measuring device is readjusted (adapted to a reference).<\/em><\/li>\n<\/ul>\n<p>We suggest the following calibration interval:<\/p>\n<p><em>1. First inspection after <strong>one<\/strong> year<\/em><br \/>\n<em> 2. After several calibrations have been made in succession, the deviation of calibration to calibration must be evaluated. Based on these data, a decision can be made to adapt the calibrating intervals.<\/em><\/p>\n<p>The following influences can lead to an increased deviation:<\/p>\n<p><em>1. No stable flow, caused by pulsating pumps, e.g.<\/em><br \/>\n<em> 2. The gas condenses or carries along liquid or dusty particles (applications with ambient air are particularly susceptible to contaminations. A filter needs to be provided here).<\/em><br \/>\n<em> 3. The effective pressure deviates considerably from the calibrated pressure (+\/- 0,2%\/bar).<\/em><br \/>\n<em> 4. The gas\/gas mixture is not consistent with the calibrated gas.<\/em><br \/>\n<em> 5. The aging of electronic components can cause changes, sometimes even improvements. Electrical changes appear as a result of aging or gradual burning of components, which impact the quality of the output signal.<\/em><\/p>\n","protected":false},"featured_media":16510,"template":"","meta":{"_acf_changed":false},"product":[3507,3509,3511,3512,3508,3510],"class_list":["post-13662","faq","type-faq","status-publish","has-post-thumbnail","hentry","product-d-flux-multi-series-en","product-red-y-compact-series-en","product-red-y-industrial-series-en","product-red-y-smart-pressure-controller-en","product-red-y-smart-series-en","product-smarttrak-series-en"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.voegtlin.com\/en\/wp-json\/wp\/v2\/faq\/13662","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.voegtlin.com\/en\/wp-json\/wp\/v2\/faq"}],"about":[{"href":"https:\/\/www.voegtlin.com\/en\/wp-json\/wp\/v2\/types\/faq"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.voegtlin.com\/en\/wp-json\/wp\/v2\/media\/16510"}],"wp:attachment":[{"href":"https:\/\/www.voegtlin.com\/en\/wp-json\/wp\/v2\/media?parent=13662"}],"wp:term":[{"taxonomy":"product","embeddable":true,"href":"https:\/\/www.voegtlin.com\/en\/wp-json\/wp\/v2\/product?post=13662"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
