Fields of application for pressure sensors 4 ? summary

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 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 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 vital that you know which sensor type can be used as the maximum error of 1 1.23 bar only leads to a measurement uncertainty of 1 1.23 bar / 1000 bar x 100% = 0.123 %. The fields of applications described here 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 precise accuracy requirements and ambient conditions should be considered.
