In previous articles concerning the fields of application of different pressure sensors, I’ve described the special features of the different versions. pressure gauge and ambient conditions are decisive when choosing the right sensor for an issue to be solved.
In smaller measuring ranges (e.g. < 10 bar), you should know whether a vented gauge pressure, non-vented gauge pressure or absolute pressure sensor can be used because, with an activity pressure of 10 bar, the indication of the measured value (1.23/10 bar x 100 % = 12.3 % measurement uncertainty) moves between 8.77 bar and 11.23 bar in line with the selected reference point (0 or 1 bar) and the varying ambient pressure (+/- 230 mbar).
In case of very high pressures (e.g. > 1000 bar), it really is becoming less and less important to know which sensor type is used because the maximum error of 1 1.23 bar only leads to a measurement uncertainty of just one 1.23 bar / 1000 bar x 100% = 0.123 %. The fields of applications described listed below are only a few selected types of the sometimes very different fields of application of the various pressure sensors and show that, in each case, the specific accuracy requirements and ambient conditions must be considered.
