I am trying to build a pressure sensor ( PSI gauge ) that will be used to measure and monitor the pressure in a pool water filter. These generally have a mechanical pressure gauge like this....
What I want to do is use this Freescale Pressure Sensor so that I can electronically monitor the water pressure in the filter. However, it is not waterproof and would mostly certainly be destroyed in little time if used to measure the pressure of a liquid.
Anybody have any idea or experience with use such a sensor in a manner that provides accurate readings while protecting the sensor from the water?
Any other methods that work well for this sort of thing?
Cost is a factor here. I can't spend a lot of money.
Edit: might something like this water pressure sender for cars work?
