The design of the UV sensor ensures that the flame detector will not react to the background radiation from hot refractory or any other source of infrared light. The UV-flame detector is equipped with an optical interface that visibly displays the intensity of the flame signal. Connects directly to the ionization or LDR input of the control box. Operations are to be in a closed area.
