The user is often faced with the question: What kind of pressure sensor should I use - a relative/gauge or an absolute pressure sensor? From food processing to petrochemical plants, to plastic injection moulding and many other industrial applications, pressure …
Measuring principles
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 …
The most common measuring principles for pressure sensors: thin-film, thick-film and piezoresitive sensors
| Michèle Beyer | PressureAlthough, for most applications, the choice of sensor measuring principle or functional principle of the pressure sensor is not important, we are still often asked about how the sensor elements integrated in our pressure sensors and pressure transmitters work. First of …
Pressure sensor principles – a comparison
| Sabine Mai | PressureThere is no “ideal” sensor principle. Of particularly great importance and widespread use are resistive sensor technologies, due to their reliability. For electronic pressure sensors, WIKA is using metal thin-film and piezo-resistive sensors. Each of the two …
