    Surface Temperature Measurements using Thermocouples--Best Practice?

    Molten, It cannot be a heat flux sensor, I need to know the surface temperature. Hacksaw, That is an interesting graph. Is it assumed that the "length" is the length of the whole wire or is it just the length of the "tip" of the thermocouple? Does thermocouple error really improve for...

    Surface Temperature Measurements using Thermocouples--Best Practice?

    racookpe1978, I want to measure the temperature of the wall at the air-wall interface. The DeltaT of the air will be 25 degrees C, and the reynolds number will vary between 400 and 2300. Hacksaw, 50 degrees is on the lower side of thermocouple sensing range but I wouldn't think that would cause...

    Surface Temperature Measurements using Thermocouples--Best Practice?

    IRstuff, Okay, I thought maybe it didnt matter, but I guess it does. I will find some paste. MintJulep, Thanks, I have been looking for something like that, just need to see if I can bend them 90 degrees. Compositepro I would prefer to be as accurate as the thermocouple type will allow...

    Surface Temperature Measurements using Thermocouples--Best Practice?

    Hello Folks, I am looking to measure surface temperature on the inside of a flat duct through which air is flowing. I plan to put holes in the surface to stick the thermocouple through, but my question is what should I do with the sensing end to get an accurate reading of the surface...
