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 …
Conversion of pressure units
| Sabine Mai | Know-howThe common units for the measurement parameter pressure are bar, psi, kg/cm², inHg and MPa, for example. In most cases, one unit has become established in a particular country or region. As a result, it often happens that one must convert a given pressure value into …
Fields of application for pressure sensors 4 – summary
| Stefan Heusel | Know-howIn previous articles about the fields of application of different pressure sensors, I have described the special features of the different versions. Pressure range and ambient conditions are decisive when selecting a suitable sensor for a problem to be solved. In …
International pressure units
| Michèle Beyer | Know-howYou must have already asked yourself once in a while why there are so many different pressure units worldwide: when are they used and which units are used most frequently and where? These questions can be answered quite easily: the SI unit for the physical quantity …
