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 …
Accuracy
Repeatability or non-repeatability?
| Michèle Beyer | Know-howAs a product manager, you sometimes face the challenge of making decisions for which there is no “right” or “wrong”. What sounds very philosophical at first has a very real background. The repeatability or, indeed, non-repeatability of a pressure switch …
Strap-on thermometer or screw-in thermometer? Temperature measurement of pipelines
| Roland Sachs | Know-howTemperature is by far the most common measurand in the industry. However, there are no general solutions for temperature measurement. Even when designing measuring points on pipelines, many different factors for selecting thermometers must be taken into account. The …
Effects of temperature-related density changes on hydrostatic level measurement
| Oleg Greber | Know-howWith hydrostatic level measurement, temperature fluctuations in the medium have an effect on the accuracy of the measurement result. But why is that, and how can you minimise the influence of temperature on hydrostatic level measurement? In the blog post “ …
Mobile calibration service
| Louisa Braunwarth-Wanka | Know-howA mobile calibration service saves time, and, with that, also money. In particular, time-critical instruments which, in an industrial plant for example, cannot be missed for long, can be calibrated with the minimum of downtime by a mobile service and thus ensuring a …
