How are absolute and relative pressure measuring ranges distinguished? There are considerable international differences. They can be explained in the following example: Europe: 0 … 10 bar / 0 … 10 bar abs America: 0 … 150 psig / 150 psia In Europe only the …

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 …
Definition of the IP68 rating in theory and practice
| Michèle Beyer | GeneralUnfortunately, we are asked too rarely regarding the specification of the IP68 rating for our pressure sensors and submersible pressure transmitters, i.e. how deep such an instrument may be submersed. However, this is not only a very meaningful question but also a …
Difference of 4-20 mA in 2-wire and 3-wire technology in pressure sensors
| Michèle Beyer | PressureWhat exactly is the difference between the 4-20 mA output signal in 2- and 3-wire technology? This question is answered best from the viewpoint of the user: An output signal in 2-wire technology means: less wiring required better EMC protection, since interferences …
