Possible heating of air by the valves

Since the valves might turn hot, I’d like to add a testcycle with a measurement of the airstreem Temperature to the testschedule, to clearify the impact. [1:28 pm, 22/10/2021] Jan Zunkler: Since oxygen is agressive, it might be an issue if valves heat it up. One would need a simple probe for the test.

Two temperature probes in the airstream would be required to measure the deltaT, and in the best case a probe on the valve itself would be perfect. This way one can measure how the valve warms up in operation, and how this affects the temperature of the qirstream. We burned a valve in operation, and I am pretty sure that this also affected the air temperature, but we never measured. So I suggested to nate to limit the current actively in the electronics design.
