For an upcoming motor test, we would like to use thermocouples (k-type?) to measure motor casing and nozzle temperatures. We would like to use an 8-channel DATAQ unit for the data acquisition. We understand there are challenges to this due to small voltage signal, non-linear temperature-voltage relationship and the need (?) for a reference junction compensation. Question to list members: Can anyone give advice on how to do this? What kind of amp would we need? Could anyone be of assistance in designing/building such? thanks in advance Richard
