The data sheet for MPX4115 series lists MPX4115AP as a "ported element". Can someone help me understand what this means and what exactly is the port used for.
Thank you so much!
Hi Megha,
The letter ”A” in the part number means “absolute” so the pressure applied to P1 is measured against the vacuum reference sealed on the P2 side:
Our differential pressure sensors can be identified by a letter “D” in the part number (e.g. MPX5100DP) and two input ports:
Please take a closer look at this article to get a better idea about pressure measurement and level of integration of NXP pressure sensors.
Best regards,
Tomas
Hi Tomas,
Thank you so much for the reply. Just one more clarification. Does interfacing with a hose/tube connection mean that the sensor can be used as a differential sensor?
Hi Megha,
Ported versions (with AP, AS or ASX suffix) allow pressure to be interfaced to a device via a hose/tube connection.
Best regards,
Tomas
