In previous articles concerning 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 selecting 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 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 using 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 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 %. Venomous of applications described listed below are just a few selected types of the sometimes completely different fields of application of the various pressure sensors and show that, in each case, the precise accuracy requirements and ambient conditions should be considered.
