Pressure Sensor and Arduino
I have not previously met the Flexscan sensors but from the datasheet it appears that there are versions of the A201 rated at 100 pounds are you committed to the 25 lbf version?

A201 datasheet here

Here is a 15 page user manual thatexplains how to produce a voltage output using a single opamp per sensor - bottom of page 9.

Many idea starters here



What is your application and why do you wish to use these sensors. These seem to be a low accuracy alternative to eg load cells and seem to be expensive for what you get. If you need 8 for your task a loadcell based solution may e cheaper.
