PROBLEM TO BE SOLVED: To provide a pressure measuring device permitting an optimum calibration depending on an individual pressure sensor unit. SOLUTION: In this device, a microcomputer 42 receives a pulse signal output from a pressure sensor unit configured so that the output pulse interval is changeable depending on a pressure to be measured imposed on the pressure sensor to calculate the pressure to be measured. On the above microcomputer 42, a ROM card 50 equipped with an IC chip 50a is attachably/detachably loaded. As the IC chip 50a contains such calibration data for discrete pressure sensor unit as data relating to temperature dependency, the microcomputer 42 utilizes these calibration data, for example, uses interpolation to calibrate and display a pressure data. |
