Conformally Coated, Non-Incendive UV Scanner with 3/4" Purge Hole and Military Connector DE701-107C and DE601- 104G
The Fireye C9701A 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 C9701A Ultraviolet Flame Scanner responds to ultraviolet (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 C9707A All Fuel Scanner should be utilized.
The C9701A Flame Scanner 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 l-inch NPT (National Pipe Thread) tapping for mounting onto a threaded sight pipe. The base also includes a 3/4-rich NPT tapping for connection of a purge air line.
- Adjustable gain control within the scanner module.
- Electronic circuitry to process and transmit an output signal.
- A mechanical "light chopper" that blocks the UV tube from light at preset intervals, testing its status.
- Scanner electronic circuitry mounted in a weather-proof cast aluminum enclosure.
- For use with R9107A Controller, see bulletin 65-8046.
- For use with 25SU3-2100 Controller, see bulletin CU-34.
