85UVF1-1CEX Fireye Cenelec Explosion Proof Housing

Overview

The Fireye 85UVF1-1CEX is a high-performance integrated flame scanner designed for use in hazardous environments. It features a Cenelec EExd IIC T6 and ATEX approved explosion-proof housing combined with an 85UVF1-1 scanner module. This microprocessor-based device utilizes solid-state ultraviolet (UV) sensor technology to detect flame flicker modulations. By incorporating an internal flame relay with automatically set ON/OFF thresholds, it eliminates the need for remote flame amplifiers or switches, simplifying the burner management system architecture.

Features

• Integrated internal flame relay with auto-adjusting thresholds.
• Microprocessor-based design using solid-state UV detection.
• Continuous electronic self-checking and full self-diagnostics for safety integrity.
• Advanced optical sensitivity for accurate flame detection across wide frequencies.
• Automatic sensor gain selection during setup routines.
• Analog 4 to 20mA output for real-time flame strength monitoring.
