UV Scanner with 3/4" Purge Hole and 50' Lead Wires DE601- 106 and DE601-104F
The FIREYE C9501N Flame Scanner provides an effective means of flame monitoring in an application where a scanner can be mounted in a direct line of sight from the flame to be monitored. The C9501N Scanner is used in conjunction with Fireye R9005, R9101, R9106 and R9105 Flame Controllers.
The C9501N Ultraviolet Flame Scanner responds to ultravilolet (UV) radiation wavelengths between 1850 and 2650 angstroms, which are emitted by natural gas and light oil (No.2) flames. If coal, heavy oil or other residual fuels are used, the C9502 Infrared Flame Scanner should be utilized.
The C9501N Flame Scanner (Figure 1) incorporates an ultraviolet sensitive detector tube, electronic circuitry to generate and transmit an output signal, a quartz viewing window and a mechanical light-blocking chopper, which is used to test detector tube status.
The scanner chassis is mounted in a weatherproof cast aluminum enclosure. The base casting and cover casting fit together and are secured with spring-loaded, half-turn fasteners. The base casting has a 1 inch NPT (National Pipe Thread) tapping for mounting onto a threaded sight pipe. The base also includes a 3/4 inch NPT tapping for connection of a purge air line.
