METHOD FOR PRESSURE MONITORING A PRESSURE-DEPENDENT PROCESS AND PRESSURE SENSOR

Method for pressure monitoring a pressure-dependent process comprising the following steps: Measuring over time a pressure of the pressure-dependent process. Processing the measured pressure by determining if the measured pressure (10, 20) or a filtered pressure obtained from the measured pressure is inside or outside defined pressure ranges (11, 12, 13, 14), each pressure range being defined by a respective lower limit (A, C, E, G) and by a respective upper limit (B, D, F, H). Generating a pressure monitoring signal in such a way that the pressure monitoring signal has a first value or first status if the measured pressure or the filtered pressure is inside a respective pressure range (11, 12, 13, 14), that the pressure monitoring signal has a second value or second status if the measured pressure or the filtered pressure is outside a respective pressure range (11, 12, 13, 14) violating a safety relevant limit (A), and that the pressure monitoring signal has a third value or third status if the measured pressure or the filtered pressure is outside a respective pressure range violating a non-safety relevant limit (B, C, D, E, F, G, H).
