Colleagues,
I need to estimate the water content in a laboratory microwave oven. The oven is used to vaporize the water out of the substrate. The goal is to turn off the generator when enough water have been removed through evaporation.
My gut feeling is that power consumption of the generator would depend on the amount of water in the chamber, provided that geometry remains the same (e.g. beaker with 100cc of sand and 50cc of water vs. same beaker with 100cc of sand 25cc of water). Have anyone used this approach for moisture content sensing? What would be a good name/keyword for such approach? Could anyone post some references to books or application notes?
Other/additional/alternative types of sensors can be used too. I can modify the oven as much as necessary (even tear it down and put together my own).
Cheers!
Have a good New Year!

P.S. At the moment the focus of this thread is the microwave approach rather than alternative sensing methods. I already know a couple of alternative approaches, and I will use some of them in addition to the one in question here.
