Fields of application for pressure sensors 4 ? summary

In previous articles concerning the fields of application of different pressure sensors, I’ve described the special features of the different versions. Pressure range and ambient conditions are decisive when choosing the right 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 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 important to know which sensor type is used because 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 listed below are only 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.
