95DSS3-1WINC Fireye Flame Scanner

Overview

The Fireye 95DSS3-1WINC InSight II is a sophisticated, microprocessor-based integrated flame scanner that combines both solid-state infrared (IR) and ultraviolet (UV) sensors into a single detection head. This dual-spectrum technology allows the device to provide superior flame discrimination and verification, accurately distinguishing target burner flames from adjacent flames or background radiation. By integrating detection, amplification, and safety determination, it eliminates the need for separate flame amplifier modules. It is the first primary safety control to be UL-certified to Safety Integrity Level 3 (SIL3), ensuring high reliability in critical safety applications.

Features

• Dual-spectrum sensing utilizing both solid-state IR and UV detectors for maximum accuracy.
• Integrated design combining detection, amplification, and flame switch functions in one unit.
• Electronic self-checking mechanism for continuous safety monitoring.
• Two independently adjustable flame relays (SPDT) and one fault relay (SPST).
• Two 4-20 mA analog outputs for signal strength monitoring of each sensor.
• 21 choices of modulation frequency (flicker) for optimized flame discrimination.
• Four selectable memory files to store parameters for different fuels or firing rates.
• Auto-configuration capability with manual override for simplified setup.
• Remote communication via optional Fireye Explorer PC software.
• Rugged NEMA 4X / IP66 rated housing for harsh industrial environments.

Applications

The 95DSS3-1WINC is specifically engineered for demanding industrial and commercial combustion systems. It is widely used in power generation, petrochemical plants, pulp and paper mills, and metal processing facilities. It is ideal for monitoring flames in multi-burner environments, industrial boilers, and furnace applications where reliable discrimination between burners is critical. The scanner is compatible with various fuel types, including gas, oil, and coal, and is often integrated into burner management systems (BMS) to provide essential safety interlocks and prevent the entry of unburned fuel into combustion chambers.
