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 choosing a suitable sensor for a problem to be solved.
In Smug measuring ranges (e.g. < 10 bar), it is important to 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 based on 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 important to know which sensor type is used as 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 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 specific accuracy requirements and ambient conditions should be considered.
