65UV5-1004 Fireye Flame Scanner

Overview

The Fireye 65UV5-1004 is a microprocessor-based, self-checking ultraviolet (UV) flame scanner designed for industrial burner management and flame safeguard applications. This integrated scanner detects UV emissions from fossil fuel flames and includes an internal flame relay, which eliminates the necessity for an external flame amplifier. The 65UV5-1004 model is now discontinued and was originally equipped with a 10-foot captive molded cable; it has been succeeded by the 65UV5-1004QD, which features a quick-disconnect fitting for easier field service and replacement.

Features

• Integrated Design: A one-piece system containing the sensor and internal flame relay for simplified installation.
• Self-Checking Shutter: Includes an electro-mechanical shutter mechanism that performs regular self-checks to ensure continuous operational safety and reliability.
• UV Detection: High-sensitivity ultraviolet tube-type sensor capable of detecting a wide range of fossil fuel flames.
• Signal Output: Provides a 4-20 mA analog output proportional to flame signal strength for remote monitoring and diagnostics.
• Status Indication: Features a two-color internal LED (visible through a rear viewing lens) to indicate flame status and fault conditions.
• Rugged Construction: Housed in a NEMA 4X / IP66 rated enclosure suitable for indoor, outdoor, and hazardous environments (Class I, Div. 2).

Applications

The Fireye 65UV5-1004 is used to monitor flames in commercial and industrial combustion systems, including industrial furnaces, boilers, process heaters, and incineration equipment. It is specifically designed to detect ultraviolet emissions from fossil fuel flames such as natural gas, propane, methane, butane, kerosene, light petroleum distillates, and diesel fuels. Its hazardous area classification makes it suitable for use in demanding environments where safety and reliable flame detection are critical.
