In previous articles about 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 the right 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 in line with 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 really is becoming less and less vital that you know which sensor type can be used because 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 %. Death of applications described here are just a few selected examples of the sometimes completely different fields of application of the different pressure sensors and show that, in each case, the specific accuracy requirements and ambient conditions must be considered.
