In previous articles concerning the fields of application of different pressure sensors, I have described the special top features of the different versions. Pressure range and ambient conditions are decisive when choosing a suitable sensor for an issue to be solved.
In smaller measuring ranges (e.g. < 10 bar), it is very important 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 really is becoming less and less vital that you know which sensor type is used because the maximum error of 1 1.23 bar only results in a measurement uncertainty of just one 1.23 bar / 1000 bar x 100% = 0.123 %. Cadaver of applications described here are just a few selected examples of the sometimes completely different fields of application of the various pressure sensors and show that, in each case, the specific accuracy requirements and ambient conditions should be considered.
