In America, the pressure type is always indicated but using another naming system (g = gauge = relative pressure). This is especially confusing if in America the pressure unit &#8220;bar&#8221; is required for an absolute measuring range or if in Europe a relative pressure device with the unit &#8220;psi&#8221; is required. How is then the correct nomenclature? The WIKA group agreed upon the following procedure: if the unit psi is used, a &#8220;g&#8221; or an &#8220;a&#8221; is added according to the American system. For all other units, we observe the European standard and only the absolute measuring ranges are marked with a separate &#8220;abs&#8221;.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How are absolute and relative pressure measuring ranges distinguished?
