I was going to work on taking two of them and connecting them to the two pressure zones using the rubber tubes. Since there are other sensors with specially made for differential measuring,I'll try using them.
I am going to measure the difference between two pressure zones,and not between one and the atmosphere.
I was going to try the differential amplifier which would've helped to measure the smaller pressure differences.
But as Billysugger mentioned, there are MPXV7002DP, Farnell part 2080499,they seem good enough and my pressure difference will not be greater than .2 kPa.
If anyone has used this/know about this sensor,if I have a pressure difference of say 0.1 or 0.001 kPa,will it be able to detect it?
Because I'll be using this to detect small pressure variations.
Thanks again for all the help.
