Bi-directional Pressure Sensor

Hi,

I am currently using the MP3V5050. Is there any sensor that can perform both negative and positive  pressure measurements from the same chip?

Can an absolute sensor measure both?

Thank you

Hi Jared,

We do have a few pressure sensors that can handle both negative pressure and positive pressure without resulting in damage in the device. This sensors are MPXV7002 (-2 kPa / +2 kPa), MPXV7007 (-7 kPa/ +7 kPa) and MPXV7025 (-25 kPa/25 kPa).

Absolute pressure sensors cannot measure negative pressure, because they are meant to measure the environment's pressure which is always positive.
