In previous articles about the fields of application of different pressure sensors, I’ve described the special features of the various versions. Pressure range and ambient conditions are decisive when choosing the right sensor for a problem 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 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 because the maximum error of just one 1.23 bar only results in a measurement uncertainty of just one 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 various pressure sensors and show that, in each case, the specific accuracy requirements and ambient conditions should be considered.
