What is the safest way to separate a process and the attached pressure measurement technology? The HSG 253 standard must be applied to this question, and it answers unequivocally: by means of an instrumentation valve with double block & bleed (DBB). This …

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 …
Pressure transducers in semiconductor manufacturing: There’s no way around UHP
Fabian Mayer | Know-howThe production of semiconductors places high demands on pressure measurement technology. Pressure transducers there, for example, are deployed in a UHP “ultra high purity”) design. This article explores the question of why such high-quality instruments are …
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 …
Sensor status always in view with diagnostic function and IO-Link
Haydar Kartal | Know-howIs the measuring instrument still working as it should? Pressure sensors with integrated diagnostic function and IO-Link provide information about their status at a glance. What this means in detail can be illustrated using the example of model A-1200 sensor from WIKA. …
