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 …
The right cable increases your machine availability
Stefan Heusel | Know-howThe choice of the right cable or line for transmitting signals on your machine has essential influence on the machine availability. Usually, when determining the instruments of machines and plants, a profound amount of attention is given to choosing the right sensors. …
Failure causes and sources of errors in sensors: Mechanical failure – defected cables, lines or connectors
Stefan Heusel | Know-howCable break / lead breakage, broken connectors and damaged cable insulation – many of these failure causes and sources of errors in sensors can be traced back to mechanical failure of qualitatively inferior components. You have carefully selected a supplier for …
Grounding of hydrostatic level sensors
Enrico Bossart | Know-howHydrostatic level sensors (also referred to as submersible pressure transmitter) are very often installed in outdoor applications, primarily in the water and wastewater industries, where open bodies of water, deep wells or boreholes are monitored. A good connection to …
