DE701-107C Fireye Scanner

Overview

The Fireye DE701-107C is a high-performance ultraviolet (UV) flame scanner electronics assembly designed for the C9701A Series. This conformally coated module is engineered for industrial and commercial combustion environments where dependable flame detection is critical for operational safety. It functions by detecting UV radiation emitted by fossil fuel flames, such as natural gas and light oil, while ignoring infrared signals from hot furnace walls or background radiation. The conformal coating provides an additional layer of protection for the internal circuitry against moisture, dust, and chemical contaminants.

Features

• Conformally coated electronics for enhanced resistance to moisture and harsh environmental conditions.
• High-sensitivity ultraviolet (UV) sensor optimized for 185 to 260 nanometer wavelength detection.
• Advanced signal processing technology ensures reliable flame discrimination and reduces false readings.
• Integrated mechanical light-blocking chopper for automated self-checking of detector tube status.
• Adjustable sensitivity potentiometer to calibrate signals based on flame size and distance.
• Rugged design for seamless integration into weatherproof cast aluminum scanner housings.
