sensors like for instance: http://www.sensortechnics.com/download/xya-637.pdfHey Robert -
I looked at the specs on that sensor and found a few things that would make it not really suitable for use underwater on a CCR. The 1.85 amps required to heat the sensor element to 700 degrees Celsius would require some serious power (like a car battery?) for any sort of dive duration. And then there is the insulation one would need to have between the loop internals and sensor to avoid melting important stuff. But don't let that discourage you. Necessity is the mother of invention, and there is plenty of innovation yet to come with regard to CCR's.
