Currently, Honeywell UV flame scanners (C7927A 1016) pointed directly at flames in a combustion chamber to detect the flame. The problem with this is keeping the scanner cool to avoid damage.
I am trying to send the UV signal through a fiber optic cable ~3 feet away using UV grade fused silica (quartz) in order to better protect the flame scanner.
The problem is I do not know much about fiber optics, and am having a great deal of trouble trying to determine how much light needs to hit the detector, and how many fibers/what fiber size I need to send an adequate amount of signal.
Also if anyone has a vendor they would recommend for the fused quartz fiber optic cable, I need around 200 feet of it.
Any help you can provide would be greatly appreciated.
Honeywell's Iris line has a commercial solution - fiber optic extension for its (formerly Iris) line of flame detectors.
It expects a steady supply of instrument grade purge/cooling air.
fiber optic cable:
A flame detector, analyzer and adapter compatible with the FO extension cable.
