Non-contact temperature measurment
Non-contact temperature measurment
(OP)
We are considering a digital radiation thermometer to monitor temperatures during steel and iron casting in the foundry.
Does anyone have experience with it or actually uses it for comparable applications (liquid steel/iron)?

I'd like to add how accurate for age hardening would you suppose these methods are?

I love materials science!

I have been told that the emissivity is of great importance and should be calibrated for each alloy. If this is done well, is it possible to measure with an accuracy of plus/minus 1°C?
Does anyone have experience with measuring the pouring stream under a bottom pour ladle?

Re accuracy: Omega Engineering has an online comparison chart for their handheld IR pyrometers. Accuracy improves from +3% to +0.25% as instrument price increases. So to within +4oC for your case. http://www.omega.com/toc_asp/frameset.html?book=Temperature&file=SEL_GUIDE_IR
Omega is a good reference info site for process measurement equipment (T, P, flow, etc.), plus they have a nice set of free handbooks which they will mail upon request. http://www.omega.com/
