In previous articles about the fields of application of different pressure sensors, I’ve described the special features of the various versions. เกจวัดแรงดันคือ and ambient conditions are decisive when choosing a suitable sensor for an issue to be solved.
In smaller measuring ranges (e.g. < 10 bar), it is important to 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 based on 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 important to know which sensor type is used because the maximum error of 1 1.23 bar only leads to a measurement uncertainty of just one 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 various pressure sensors and show that, in each case, the specific accuracy requirements and ambient conditions should be considered.
