UV Detectors UVS

The UVS UV detector monitors gas burners of unlimited capacity with or without fan, on hot-air furnaces, gas-fired boilers, industrial furnaces and excess-gas flaring installations in conjunction with the PFU 780 burner control, the PFU 760 burner control, the IFS 110IM burner control or BCU series automatic burner controls.

Features

• The UV sensor monitors the gas burners in intermittent operation
• The burners can either be ignited directly or operated as pilot and main burners
• Suitable for small burners due to high sensitivity
• Virtually immune to interference due to its insensitivity to daylight, infrared radiation and incandescent bulbs
• Maximum safety thanks to protection against discontinuity or short-circuit on the flame signal cable
• Lower logistics costs as the UVS 10 replaces several previous models
• Suits industrial needs due to robust design
• Complies with the requirements of EN 298 in conjunction with Elster Kromschroder automatic burner control units
• UV sensors UVS 1, UVS 6 and UVS 8 can be replaced by using various adapters

	Applications Click on images for close-up view. Features The UV detector responds to the ultraviolet light of a flame. It does not react to daylight, incandescent lamps, infrared radiation, hot work-pieces or incandescent furnace walls. The UVS 6 is complete with a quartz lens, which isolates the detector from the hot furnace atmosphere against humidity, dirt and heat. A quartz lens is not necessary for the UVS 8 detector. Overheating, dirt and condensation can be avoided with cooling as shown in the diagram below. Max lead length between UV detector and automatic burner control is 150 feet (50 m), if plastic conduit is used. If metallic conduit is used, this length should not exceed 50 feet (15 m). The maximum recommended sighting distance between the UV detector and the flame is 16" (400 mm)
