In previous articles about the fields of application of different pressure sensors, I’ve 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 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 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 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 can be 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 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.
