Patented High Temperature Pyrometer Camera
The IST-Quadtek

Spyrometer

, with its patented combi-
nation of a color video camera and a scanning pyrometer, 
gives the operator the ability to see process conditions 
while measuring the temperature of virtually any area in the 
field of view. The M555 imaging pyrometer takes the video 
image and the temperature information, multiplexes it and 
sends it, via coaxial cable, to the image processor in the 
control room and displays it on a VGA monitor. Onscreen 
temperature measurement data is also accessible through 
4-20mA outputs which can easily be interfaced to your 
control system.
