In previous articles concerning the fields of application of different pressure sensors, I have described the special features of the various versions. ไดอะแฟรม ซีล and ambient conditions are decisive when choosing a suitable 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 using 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 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 just one 1.23 bar / 1000 bar x 100% = 0.123 %. The fields of applications described here are just 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 must be considered.
