Measurement range and overpressure protection Range: It is necessary to cover the actual working pressure and leave a margin of 20%-80% to ensure the best accuracy. For example, a chemical plant reactor pressure monitoring uses a model with a range of 0-10MPa, and the data stability is improved by 30% in actual use. Overpressure protection: It is necessary to ...
