Clean air is being passed through the chamber. The reading were taken after allowing system to stabilize for 5 minutes. Day 1 reading for output voltage was 1.22 V (corresponding pressure value = 102.2865 KPa), and day 2 reading for output voltage was 1.18 V (corresponding pressure value = 99.0469 KPa), although all the system parameters were maintained.</P><P></P><P>Kindly explain the reason for the difference.</P></BODY></HTML> Tue, 03 Feb 2026 22:53:28 GMT https://community.nxp.com/t5/Sensors/MPXH6400A/m-p/451911#M2404 saurabhbhansali 2026-02-03T22:53:28Z Re: MPXH6400A https://community.nxp.com/t5/Sensors/MPXH6400A/m-p/451912#M2405 <HTML><HEAD></HEAD><BODY><P>Hello,</P><P></P><P>A possible reason for this difference might be the <STRONG>temperature</STRONG>. </P><P></P><P>Please be aware that the maximum error over 0 °C to 85 °C is <STRONG>1.5% </STRONG>in the MPXx6400A device. </P><P></P><P>Are you exposing your application to temperature changes? </P><P></P><P></P><P>In order to get more information about the temperature error, please refer to the figure bellow:</P><P></P><P><span class="lia-inline-image-display-wrapper" image-alt="temperature error band.jpg"><img src="https://community.nxp.com/t5/image/serverpage/image-id/21544iF511AFB32C054F88/image-size/large?v=v2&amp;px=999" role="button" title="temperature error band.jpg" alt="temperature error band.jpg" /></span> </P><P></P><P>I hope this information will be useful for you.</P><P>If I misunderstood your question, feel free to let me know.&nbsp; I will be glad to help.</P><P></P><P>Have a great day.</P><P>David Diaz.</P></BODY></HTML> Tue, 19 Jan 2016 18:25:14 GMT https://community.nxp.com/t5/Sensors/MPXH6400A/m-p/451912#M2405 david_diaz 2016-01-19T18:25:14Z
