In previous articles about the fields of application of different pressure sensors, I have described the special top features of the different versions. Pressure range and ambient conditions are decisive when selecting a suitable sensor for a problem to be solved.
In Child-like 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 important to know which sensor type can be used because the maximum error of just one 1.23 bar only leads to a measurement uncertainty of 1 1.23 bar / 1000 bar x 100% = 0.123 %. Smiling of applications described here are just a few selected types of the sometimes completely different fields of application of the different pressure sensors and show that, in each case, the precise accuracy requirements and ambient conditions should be considered.
