In previous articles about the fields of application of different pressure sensors, I have described the special features of the different versions. Pressure range and ambient conditions are decisive when selecting the right sensor for an issue 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 a process 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 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 1 1.23 bar / 1000 bar x 100% = 0.123 %. Super of applications described here are only a few selected examples 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 must be considered.
