This Fireye UV scanner detects ultraviolet radiation emitted by flames. It connects using a 1/2" NPT fitting and includes a 6-foot cable (shielded). The device monitors flame presence in combustion systems, ensuring safe operation by providing real-time feedback to control systems.
The UV1A series scanner is an ultraviolet miniature non-self-checking scanner suitable for fuel gases and no. 2 oil. It has a non-replaceable tube. The UV tube is made of quartz and is filled with a gas that ionizes when struck by UV radiation from the flame. In the absence of UV radiation, the gas acts as an insulator between two electrodes mounted inside the tube. These electrodes are energized continuously by a high voltage. During combustion, UV radiation ionizes the gas, causing current pulses to flow between the electrodes. These current pulses result in a flame signal transmitted to the amplifier in the control, where it is processed to energize or hold in the flame relay.
