https://community.nxp.com/t5/LPC-Microcontrollers/MPX2102/m-p/1997154#M57288 <P>Hi,</P> <P>The MPX2102GP is intended to measure pressure in one direction only. Our datasheet characteristics and specifications are reflecting this official way of operation only.</P> <P>Being said that, when using the MPX2102GP, it is possible to apply a negative pressure up to 100 kPa and you will get a negative differential voltage on the output. The sensor will not be damaged.</P> <P>BRs, Tomas</P> Tue, 19 Nov 2024 11:44:11 GMT TomasVaverka 2024-11-19T11:44:11Z https://community.nxp.com/t5/LPC-Microcontrollers/MPX2102/m-p/1996973#M57287 <P>MPX2102AP测试的是绝对压力，现在想用MPX2102GP做替换，想问下能不能用MPX2102GP去测试相对压力为负值的情况，如果不能，有没有其他型号可以代替的。</P> Tue, 19 Nov 2024 08:51:40 GMT https://community.nxp.com/t5/LPC-Microcontrollers/MPX2102/m-p/1996973#M57287 ZIMO 2024-11-19T08:51:40Z https://community.nxp.com/t5/LPC-Microcontrollers/MPX2102/m-p/1997154#M57288 <P>Hi,</P> <P>The MPX2102GP is intended to measure pressure in one direction only.
