There are many reasons for using electrical thermometers with short response times: optimisation of the efficiency, more efficient utilisation of the working range of a process, avoidance of thermal overload of the process medium. But how are response times measured, …

Temperature calibration: Thermocouples vs. resistance thermometers
Katja Strecke | Know-howIn temperature calibration, high demands are placed on reference thermometers in terms of accuracy and reproducibility and thus long-term stability. Therefore, RTDs (“resistance temperature detectors”) – here specifically platinum resistance thermometers – and …
Natural gas: On-site calibration optimised at the metering skid
Jing Lyu | ApplicationsOn-site calibration of measuring instruments is often very time-consuming and expensive. This is especially true for applications with several measurands. One example of this is the metering skid, a system for the custody transfer measurement of the amount of natural …
China Compulsory Certification (CCC) for electrical thermometers
Joachim Brückner | TemperatureThe “China Compulsory Certification (CCC)” is a certification system of the People's Republic of China. Since 1 October 2020 it is, for example, no longer permissible to place explosion-protected electrical thermometers (resistance thermometers and thermocouples) …
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 …
