Oxygen, the gas essential for life, is far more complex in industrial applications than our daily inhalation and exhalation suggests. Industry – especially in the chemical, pharmaceutical or medical engineering fields – is, time and again, finding itself confronted …

Filling liquids in pressure gauges: Usage and advantages
Sandra BroßlerLiquid-filled pressure gauges are used in applications that involve high dynamic shock and vibration loading. The filling liquid dampens the vibrations that occur and thus takes the load off the mechanical components of the pressure gauge. Depending on …
How do diaphragm seals work?
Jennifer BreunigDiaphragm seals, also known as chemical seals or remote seals, are used for pressure measurements when the process medium should not come into contact with the pressurised parts of the measuring instrument. A diaphragm seal has two primary tasks: 1. Separation of …
Fields of application for pressure sensors 3 – Absolute pressure sensors: why is it necessary to use absolute pressure sensors or pressure transmitters
Stefan HeuselElectronic pressure sensors usually measure the change in pressure through the deformation of a diaphragm. If this diaphragm is exposed to the process pressure on one side and "vented" on the other side (and thus exposed to the ambient pressure), the deformation is …
Fields of application for pressure sensors 2 – non-vented gauge pressure sensors: when unvented pressure sensors or transmitters are the best choice
Stefan HeuselIn most applications, gauge pressure measurement is required and therefore pressure sensors and pressure transmitters that measure pressure against the prevailing ambient pressure are commonly used for this. Those pressure sensors typically have a venting hole to …
