The accuracy of MPXH6400A

Question asked by weiyuan zhang on Jun 29, 2017

Hi there,

I am using MPXH6400A for measuring water pressure. From the document about MPXH6400A the error should be +- 5.5 kPa as shown in the following figure. While from the my experimental observation, the pressure vs. time curve was very smooth. I am now so confused about the error band because I will put several sensors into water only around 20 cm. Does it mean that due to the low water pressure the outcome will not be acceptable?

So my question is that what is accuracy of this sensor?

Best regards,
