UV flame detector for the rough industrial environment in non continuous operation.
The IFX series is characterized by its robust die-cast aluminum housing with IP65 protection. The housing design allows quick replacement of the device on site.
The IFR 11 is a compact UV flame detector, which is specially designed for severe conditions often experienced in industrial applications for single flame combustion. The IFR 11 can be connected directly to the ionisation or LDR input of the control box. The UV sensor ensures that the flame detector does not react to background radiation from hot refractory or from any other infra-red light source.
The compact UV flame detector has to be disconnected started up once in a day.For safety reasons and technical regulations a controlled burner shut down at least once per 24 hours must be guaranteed.
The UV flame detector IFR 11 has been developed to meet the requirements of UL 372-2, CSA C22.2 and EN 298. The internal 15 % increase of the UV tube voltage during the start-up phase ensures the safety requirement for the examination of the UV tube to through-ignition. The UV flame detector IFR 11 has to be switched off for more than 5 seconds before burner operation can be started again. A simple change from ionisation flame control to the IFR 11 is permissible therefore also with control boxes without own UV tube input.
The UV flame detector is equipped with an optical interface which visibly indicates the flame signal intensity. A simple diagnosis of the flame intensity is directly on the furnace boiler possible.
