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 at …
Thermometer calibration – an overview
| Danica Schwarzkopf | Know-howNot 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 …
Ice cold – Electrical thermometers in low ambient temperatures
| Joachim Brückner | Know-howMedium temperatures of -60 °C don't even make the designers of electrical thermometers shrug their shoulders – but when one speaks of ambient temperatures of -60 °C, then one often hears a sharp intake of (cold) breath. It quickly becomes clear that one cannot …
