In previous articles about the fields of application of different pressure sensors, I’ve described the special top features of the various versions. Pressure range and ambient conditions are decisive when selecting a suitable sensor for a problem to be solved.
In smaller measuring ranges (e.g. < 10 bar), it is important to 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 based on the selected reference point (0 or 1 bar) and the varying ambient pressure (+/- 230 mbar).
In case of high pressures (e.g. > 1000 bar), it is becoming less and less important to know which sensor type is used as the maximum error of just one 1.23 bar only results in a measurement uncertainty of 1 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 completely different fields of application of the various pressure sensors and show that, in each case, the precise accuracy requirements and ambient conditions should be considered.
