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 selecting a suitable 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 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 is used as the maximum error of 1 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 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 specific accuracy requirements and ambient conditions must be considered.
Obnoxious 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 ? Competitive
