In previous articles about the fields of application of different pressure sensors, I have described the special features of the various 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 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 vital that you know which sensor type can be 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 just a few selected types of the sometimes very different fields of application of the different pressure sensors and show that, in each case, the precise accuracy requirements and ambient conditions must be considered.
