can the MPXx6250A be used as a vacuum sensor?

[rodschulz]

I have an automotive application and want to know if the MPXx6250A can be used as a vacuum sensor?  My vacuum levels are ~ 14inHg to 24inHg.

Hello Rod,

Thank you for writing.

As we know, the MPXx6250A is an absolute pressure sensor. The absolute pressure is the difference between the pressure at a given point and the absolute zero of pressure or a perfect vacuum. In other words: pressure is applied on Port P1 of the sensor while the Port P2 of the sensor is a vacuum sealed reference.

The pressure range of the MPXx6250A is from 20 kPa to 250 kPa (5.906 inHg - 73.825 inHg), which is within the levels mentioned.

I assume the device is useful for your application.

Please let me know if I understood your question.

Best Regards,

David
