MPX2102AP替换

[ZIMO]

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。

Hi,

The MPX2102GP is intended to measure pressure in one direction only. Our datasheet characteristics and specifications are reflecting this official way of operation only.

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.

意思就是说，虽然MPX2102GP在规格书上是说用来测表压，相对压力大于零情况的，但实际上如果我现在要测相对压力负压也是可行的是吧

Hi,

Yes.
