When one looks at it objectively, most industrial plants constitute a hazardous zone. Many materials necessary for process operation, and also finished products, are flammable or explosive. The more of these materials are needed for the manufacturing process or are …
Operating conditions
New ScrutonWell ® design for thermowells
| Kai Grabenauer | TemperatureIn order to avoid any damage to the thermowell during operation due to mechanical loads, a thermowell calculation per ASME PTC 19.3 TW-2016 is recommended for critical process conditions. In case of a calculation with negative results, the only constructive solution so …
Difference between gauge pressure and absolute pressure
| Michèle Beyer | Know-howThe question about the difference between an absolute pressure and a gauge (relative) pressure measurement always pops up every now and again. From a purely theoretical point of view, the question can be answered relatively easily: in a gauge pressure measurement …
Aim and purpose of a vent hole in pressure sensors
| Michèle Beyer | PressureIn so-called “gauge sensors” pressure is always measured relative to the currently prevailing ambient pressure. However, the ambient pressure is by no means constant. It is location- and height-dependent and changes with the weather. This means that for a …
