from the environment, while allowing the pressure signal to
be transmitted to the silicon diaphragm. The MPXxx6115A
series pressure sensor operating characteristics, internal
reliability and qualification tests are based on use of dry air as
the pressure media. Media other than dry air may have
adverse effects on sensor performance and long-term
reliability. Contact the factory for information regarding media
compatibility in your application.
