infrared temperature sensor emissivity
infrared temperature sensor emissivity
(OP)
I am looking for an Infrared sensor for measuring TIG welding temperature at every pass (interpass temperature). Should I go for a fixed or variable emissivity instrument?
What is the difference between the two realy?
I am welding Inconel pipe ID.
Thanks!

RE: infrared temperature sensor emissivity
Are you talking about the temperature of a glowing weld or a just a large piece of clean metal? What kind of temps are you expecting?

I am expecting about 275-325F.

You might want to check with someplace like Omega.com to see what they suggest.
Or get a really handy unit like: h
to experiment with, since it allows emissivity adjustments and is inexpensive.I use one like this weekly for something or other.
If this is for production monitoring then with shiny stuff you are often much better off with a rolling thermocouple.
