Standard 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 …
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 …
Measurement technology in compressors
Roland Sachs | ApplicationsThe measurement technology used in compressors is tending to increase more and more. And for good reason. The balancing act between increased compressed air demands and reduced energy consumption also depends, to a large extent, on the intelligent use of measuring …
Application of sapphire thermocouples in gasification reactors
Kai Grabenauer | TemperatureGasification reactors, due to their harsh process conditions, place high demands on the instruments used there. Many manufacturers have reacted to this and adapted their products correspondingly. But what are the optimisation possibilities for thermocouples for use …
