45UVFS1-1000EX Fireye HOUSING & Scanner

Overview

The Fireye 45UVFS1-1000EX is an explosion-proof ultraviolet (UV) flame scanner designed for use in hazardous locations. This advanced, microprocessor-based “Signature Scanner” is engineered to provide reliable flame detection and exceptional discrimination in multi-burner environments. It features a self-contained design that integrates the sensor and amplifier into a single, robust aluminum housing, utilizing specialized software algorithms to analyze and compare flame frequency and amplitude against a stored target signature to prevent false signals from adjacent burners.

Features

• Signature Technology: Employs a microprocessor to learn and store a unique flame signature, ensuring high discrimination against background radiation and other burner flames.
• Integrated Display and Keypad: Features an eight-character LED display and a three-button keypad for local programming, setup, and reviewing operational parameters.
• Explosion-Proof Housing: Mounted within a NEMA 7 rated enclosure designed for Class I, Division 1 & 2 (Groups C, D) and Class II, Division 1 & 2 (Groups E, F, G) environments.
• Multi-Fuel Compatibility: Suitable for monitoring flames from natural gas, oil, and coal.
• Self-Checking Circuitry: Includes an electromagnetic shutter to periodically block the optical path, allowing the system to verify the integrity of the scanner and signal circuits.

Specifications

• Model Number: 45UVFS1-1000EX
• Operating Voltage: 24 VDC (typically powered by compatible Fireye controls)
• Spectral Response: Ultraviolet (UV) using a “super-blue” silicon cell
• Housing Rating: NEMA 7, Class I, Div 1 & 2, Groups C & D; Class II, Div 1 & 2, Groups E, F & G
