Hello,
I'm not sure that this is the best forum to discuss this topic, but I'll give it a try.
I have need of a high temperature CCTV camera for monitoring the area around a nuclear reactor cooling loop. The ambient temperature while operating I'm told is about 150-160 degrees F.
Right now we have a 1/3" color CCTV camera with PT and an 8-24mm zoom lens mounted in a fabricated metal housing box controlled from a remote controller outside the loop area. We were burning up cameras, then I found that almost every off the shelf camera is only rated for ~120 degrees max. Our lenses also experience "browning." What causes this? Is it related to high temperature, radiation exposure, or both?
I've seen very sophisticated high grade auxiliary cooled cameras as for refractories, etc. I've also seen Peltier cooled cameras (I think best solution so far), but Peltiers draw LOTS of current I'm told. Maybe a housing within a housing filled with coolant?
Is there a way to cool the camera within the housing when the air outside the housing is 160 deg.f.? If anyone has a lower priced solution to the refractory camera style? Is there an off the shelf camera good for higher temps that you are aware? I'd like to compare some ideas with everyone about this. Any experience?
Thanks,
