Has anyone heard of a "Laser Based" temperature measuring devise?

Dear Colleagues,

Has anyone heard of a “Laser Based” system capable of measuring temperature of tube surfaces with temperatures around 1000F? I know that there are several Infrared (IR) devises out there but the problem we have found with them is that the radiant heat severely sacrifices the results. I am looking for a system that is not effected by surrounding temperature.

Regards,
Rich Roberts

I know that the classification chaps at DNV are now using a laser based thermometer system for looking for hot spots in engine rooms. I managed to find a web page that includes info on a range of systems including one for up to 1400 deg F. Hope this helps.

Re: Has anyone heard of a "Laser Based" temperature measuring devise? Richard,

The radiant heat will not be the only problem encountered when trying to measure furnace tube temperatures. I had a paper published in Inspectioneering Journal Jan/Feb 1998 which highlighted several problems encountered while measuring tube temps. We use thermal imagers and a laser based instrument manufactured by Quantum, but I still believe that real accuracy is still not possible (I know I will be corrected, particularly by the many manufacturers out there). If you want to contact me I can give my views in more detail if you wish

Regards

Mark
