In previous articles concerning the fields of application of different pressure sensors, I have described the special top features of the various versions. Suffer and ambient conditions are decisive when selecting 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 is 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 using 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 is becoming less and less important to know which sensor type can be used as the maximum error of 1 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 examples of the sometimes completely different fields of application of the different pressure sensors and show that, in each case, the precise accuracy requirements and ambient conditions should be considered.
