65UV5-1004ECEX Fireye Integrated Flame Scanner

Overview

The Fireye 65UV5-1004ECEX is a microprocessor-based, integrated ultraviolet (UV) flame scanner designed for industrial burner management and flame safeguard applications. This self-checking unit combines a flame sensor and a control relay into a single, compact housing, eliminating the need for an external flame amplifier. It is specifically engineered to replace the 65UV5-1004CEX model and is designed for use in hazardous locations, featuring a rugged construction that monitors fossil fuel flames with high sensitivity and reliability.

Features

• Integrated Design: A true one-piece system that includes an internal flame relay and requires no external amplifier.
• Self-Checking Technology: Utilizes an electro-mechanical shutter mechanism to continuously verify the scanner’s operational integrity.
• Signal Output: Provides a 4-20 mA analog output referenced to flame signal strength for remote monitoring and diagnostics.
• Quick Setup: Designed for “out of the box” operation with minimal programming or setup required.
• Status Indication: Features a color-coded internal LED, viewable through a rear port, to indicate flame status and alarm conditions.
• Durability: Housed in a NEMA 4X (IP66) rated enclosure suitable for harsh industrial environments.

Specifications

• Model: 65UV5-1004ECEX
• Flame Failure Response Time (FFRT): 1 second (indicated by the “E” version).
• Input Power: 24 VDC (+10%, -15%).
• Relay Output: Internal single-pole, single-throw (normally open) flame relay.
• Analog Output: 4-20 mA DC.
• Mounting: 1-inch BSP mounting threads for sight pipe and 3/4-inch cooling air connections.
• Temperature Rating: -40°F to +150°F (-40°C to +65°C).
• Hazardous Area Classification: Suitable for Class I, Division 2, Groups A, B, C, and D; also ATEX/Ex II3 G/D Ex nA IIC T4A.

Applications

The 65UV5-1004ECEX is used to detect ultraviolet radiation from various fossil fuel flames, including natural gas, propane, methane, butane, kerosene, and diesel fuels. It is commonly applied in oil and gas refineries, chemical processing plants, and other industrial facilities where dependable flame monitoring is critical. The scanner is ideal for applications where space is limited or where a simplified, integrated detection system is preferred over separate scanner and amplifier components.
