The extension of a flanged diaphragm seal system using a flushing ring brings significant advantages. Among other things, it enables easy cleaning and, in addition, on-site calibration of the measuring location. Diaphragm seal systems are used in processes with …
Calibration
Why the calibration of (force) measuring instruments is important
| Markus Heidl | Calibration, ProductsEveryone 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 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 …
