Product Description

Wholesale Price Original Siemens QRA55.E27 UV ir Flame Detector Sensor Tester For Boiler Part

Application

This type of flame detector monitors the flame signal produced by UV radiation emitted by a gas or oil flame. The radiation detector is a UV phototube with 2 electrodes, which when illuminated by light in the 190...270 nm range of the spectrum will  initiating current in the flame detector circuit. UV does not react to hot refractory bricks in the combustion chamber, sunlight or lighting rays.

 Warning notice
To avoid personal injury, property damage and environmental damage, the following warning notices must be observed!
Do not open, interfere with or modify the flame detector! • All activities (installation, assembly and service work, etc.) are to be carried out by professionals
• Fully isolate the equipment from mains (all two stages disconnected) before making any wiring changes in the detector's connection area.
• Provide adequate protection to connection terminals from electrical shock.
• Check to make sure the wiring is properly connected.
• Halogen lamps, welding equipment, special lamps, or ignition sparks may generate enough radiation to cause the detector's UV Unit is lit. X-rays and gamma rays can also cause false flame signals.
• A fall or impact can affect the safety function. Such detector units do not work, even though they appear to be No damage at all. Installation Precautions
• Ensure compliance with relevant national security rules Installation Guide
• Controller unit and other cables must be installed separately from high voltage ignition cables Electrical connections for flame detectors To exclude interference, it is important to avoid losses in signal transmission:
• Do not run detector cables with other cables - Line capacitance reduces the level of the flame signal - Use a separate cable
• Observe the permissible length of the detector cable.
