I am relatively new to thermocouples. We are wanting to get the temperature of fire ball blast. We are using a Type-K thermocouple and a Phoenix Contact mini signal conditioner to amplify the signal. I am using a thermocouple DAQ to record the amplified voltage out from the signal conditioner (a 0-5V analog output) with a 150ms sampling period.
Questions I have:
- Do I require cold junction compensation? If so, is it best to just set it to 0°C? If not, how do I find out what it needs to be?
- What is the best way to calibrate it and how do I convert the amplified signal (V) back into a relative temperature (°C)?
