Pressure Sensor MPX2202AP

Hi, I want to use the pressure sensor MPX2202AP (absolute pressure). The datasheet says, that pressure is limited to 20 kPa abs., but I want to measure down to approx. 0 kPa abs. So my question is, why is the sensor limited to 20 kPa abs. and what will happen, if the sensor will be applied with 0 kPa abs. I think that the backside of the sensor is fully evacuated an so it should be no problem to apply the sensor to 0 kPa abs?! Output signal can go to negative values?! Ok, no problem in my application. Thankys for any help!

Best Regards

Nils
