Everyone involved in measurement technology knows the somewhat flippant – but very catchy – statement: “If you measure a lot, you measure nothing!” What is meant by this is: You can measure a lot. But the values are only useful if you can validate them. In …
Calibration
Calibration of ultra-high pressures over the entire measuring range
Jing Lyu | ApplicationsThe calibration of ultra-high pressures is a challenge. This is because conventional test instruments are only designed for pressures up to 1,000 bar. In many applications, however, sensors work with several times this value, for example in the automotive industry. If …
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 …
Temperature calibration with reference probes, dry-well calibrators and baths
Katja Strecke | Know-howCan dry-well calibrators and calibration baths be used as internal references? Temperature dry-well calibrators and baths are a practical solution for temperature calibrations. This is true both in the field and in laboratories, as they provide a free-standing, stable …
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 …
