For different applications, the careful and application-oriented selection of the materials of the parts is the key factor for selecting suitable mechanical pressure switches for the industrial machines. The medium and medium temperature are critical factors for an …

Hydrogen and pressure sensors – What must be observed when using the medium hydrogen?
| Michèle Beyer | ApplicationsWhen pressure sensors come into contact with hydrogen, this often results in difficulties. Unfortunately, I very often notice in my job that our customers are not aware of this prior to use. This is why they often do not even tell us that their medium contains …
Positive material identification test (PMI)
| Kai Grabenauer | Know-howThe positive material identification test - PMI test - serves as a proof of the alloying constituents present in the material, confirming the melting analysis of the material contained in the 3.1 certificate. There are two different test procedures common for …
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 …
What does “adiabatic compression” mean and what is a pressure-surge test?
| Stefan Heusel | Know-howThe term adiabatic compression refers to an abrupt temperature increase as a consequence of a pressure surge. Such temperature increases occur in gaseous media, when the thermal energy which is released due to a change in pressure cannot be passed on to the environment …
