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 choosing a suitable sensor for a problem 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 is 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 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 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 %. Economical of applications described listed below 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 must be considered.
