In previous articles concerning the fields of application of different pressure sensors, I’ve described the special top features of the different versions. Covert 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 is 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 as 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 here are only a few selected types 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.
