Hi All,
I have an application where I need to sense the changing opacity of a substance in an environment (chamber) where the temperature is steadily increased. I have set up a high temperature fiber optic glass cable set configured as a thru beam with the substance in the sensor gap. The question that I have is this....if I use an infrared type photo transistor emitter/collector to shoot thru the fiber optic cable will my results skew just because of the increased infrared light with the increasing temperature regardless of the opacity? If this is the case, what would be the recommended wavelength of LED emitter/receiver pair that would have immunity to heat?
Thanks,
Scott
