Fields of application for pressure sensors 4 ? summary

In previous articles about the fields of application of different pressure sensors, I’ve described the special features of the different 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), you should 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 based on 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 is 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 listed below are just a few selected types of the sometimes very different fields of application of the different pressure sensors and show that, in each case, the specific accuracy requirements and ambient conditions must be considered.
