Again and again, we are asked the question about the difference between an absolute pressure measurement and a gauge pressure measurement. To answer this question it helps to look at the definition of gauge pressure and absolute pressure. The difference between the two …
Not all calibrations are the same. This is illustrated by the example of “Thermometer calibration” - which test method is used depends on various factors such as process conditions, quality standards and safety requirements. Depending on the method, the calibration …
Validation of calibration software - as required by ISO 17025, for example - is a topic that people don't like to talk about. Often there is uncertainty about the following: Which software actually must be validated? If so, who should look after it? Which requirements …
Vibrations can sometimes violently load Bourdon tube pressure gauges. They cause pointer flutter and also, in the event of sustained loading, damage to the measuring system, even to the point of total failure. The most effective protection against these effects is …
The DIN 3852-E pressure connection thread standard has been invalid since 2012. The standard that has been valid since then for pipe threads (e.g. for G ¼ A) is DIN EN ISO 1179-2: “Connections for general use and fluid power - Ports and stud ends with ISO 228-1 …
