95UVS4-1WINC Fireye Scanner

Overview

The Fireye 95UVS4-1WINC is a microprocessor-based ultraviolet (UV) flame scanner from the InSight Series 4, designed for precise and reliable flame detection in industrial burner management and combustion control applications. This integrated unit combines flame detection, amplification, and safety relay logic into a single compact housing, eliminating the need for a remote flame amplifier. It utilizes solid-state UV sensing technology to accurately detect flame presence while actively discriminating against background radiation. The -1WINC model is specifically designed with a twelve-pin electrical quick-disconnect compatible with 59-608, 59-547, and 59-497 cables.

Features

• Solid-state UV flame detection with advanced signal discrimination technology.
• Integrated flame detection, amplification, and safety relay in one unit.
• Electronic self-checking operation eliminates the need for a mechanical shutter.
• Built-in two-line, 16-character alphanumeric OLED display with a five-button keypad for on-site configuration and diagnostics.
• Adjustable flame relay ON/OFF thresholds and sensor gain for precise control.
• 21 selectable modulation frequencies to optimize performance for various fuels and burner types.
• Dual 4-20 mA analog outputs for continuous signal strength monitoring and integration.
• Four selectable memory files for storing configuration settings for different fuels or firing rates.
• SIL 3 certified for high-integrity safety applications.
