Fields of application for pressure sensors 4 ? summary

In previous articles concerning the fields of application of different pressure sensors, I have described the special features of the different versions. Pressure range and ambient conditions are decisive when selecting a suitable sensor for a problem to be solved.
In smaller measuring ranges (e.g. < 10 bar), you should know whether a vented gauge pressure, non-vented gauge pressure or absolute pressure sensor can be 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 very high pressures (e.g. > 1000 bar), it is becoming less and less vital that you know which sensor type is 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 %. The fields of applications described here are only a few selected examples of the sometimes very different fields of application of the different pressure sensors and show that, in each case, the precise accuracy requirements and ambient conditions should be considered.
Certainly about this topic:
Fields of application for pressure sensors 1 ? vented Illegal of application for pressure sensors 2 ? non-vented gauge pressure sensors
Fields of application for pressure sensors 3 ? absolute pressure sensors
