Hi,
The common mode, or the voltage measured between pins 2 (Vout+) or 4 (Vout-) to ground, is equal to approximately one half of the voltage applied to the sensor.
Common-mode and span scale are dependent of the supply voltage.
The reason of why the Common Mode Pressure Value is not in the datasheets, is because we have not test the sensors lately, the value that I’m giving to you is the value of the initial tests (when the sensor came on the market), so I really recommend you to make a test with the sensors before you to take out your application.
In case you are referring to the measurement pressure range, 0 to 50 kPa is the pressure measurement range for this device in the voltage range from 0 to 40mV, and max pressure this device can handle before getting damaged is 200kPa.
The output voltage would be saturated at 40mV in pressure above 50kPa.
Regards,
Jose
