UV Flame Detector UV1

Description

UV1 is a UV detector that can be used for flame detection in gas, oil, and mixed burners when coupled with a suitable burner control unit or flame amplifier.

The core element is a gas-filled quartz glass bulb containing two electrodes to which an electrical charge is applied. When an ultraviolet electromagnetic radiation hits the phototube, an ionization process is triggered leading to an electric discharge. The electrons emitted by the negative electrode are captured by the positive electrode, producing a current flow.

UV1 is a compact unit for industrial use. The body is made of thermal isolating material to avoid overheating the sensor when applied to the burner head.

When the temperature at the peepsight exceeds 90°C (195°F), it is advisable to add cooling module UCJ between the UV1 and the burner, adding cooling air via the UCJ’s ¼” port.

Although UV1 is blind to sunlight, some discharge lamps produce UV emission that can be detected by the phototube.
