In previous articles about 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 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 in line with 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 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 only a few selected types of the sometimes completely 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.
Wanted about this topic:
Fields of application for pressure sensors 1 ? vented gauge pressure sensors
Fields of application for pressure sensors 2 ? non-vented gauge pressure sensors
Fields of application for pressure sensors 3 ? absolute pressure sensors
