[SS2S-Main] temperature measurement

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
