Pressure and temperature measurement at extremely low ambient temperatures
Christopher Ott | Know-howStandard pressure gauges and thermometers generally cope with ambient temperatures down to -40 °C. But what must be the features of a mechanical measuring instrument that works perfectly well in polar climates with even lower temperatures? This can be explained using …
Pt100 in class B or F 0.3 – what does IEC 60751 say?
Roland Sachs | Know-howPerhaps you've already noticed that in some instances a Pt100 is specified with an accuracy class B or A. At other times, it has the class F 0.3 or F 0.15. This blog post looks at the specifications for Pt100 in the international IEC 60751 standard and explains the …
Filter monitoring: A crucial component for energy-efficient operation
Jürgen Arndt | Know-howIf the careful use of “energy” as a resource used to be for cost reasons, today there is also increased environmental awareness. All of this also becomes mandatory thanks to legal requirements and the state of the technology. In this article you can read about how …
Calibration bath or dry-well calibrator – which is the right choice?
Danica Schwarzkopf | Know-howTemperature sensors – like all other sensors – must be calibrated at regular intervals. This ensures that they deliver accurate and consistent measured values. Temperature calibration (e.g. using a calibration bath or dry-well calibrator) is generally carried out …
