Overview
The Fireye 65UV5-1000 is a unitized, integrated flame scanner part of Fireye’s Simplicity line. This self-checking scanner detects ultraviolet emissions from fossil fuel flames such as natural gas, coke oven gas, propane, methane, butane, kerosene, light petroleum distillates and diesel fuels. The 65UV5 flame scanner is a microprocessor-based flame scanner utilizing an ultraviolet tube-type sensor and an electro-mechanical self-checking shutter mechanism. The Fireye 65UV5 flame scanner incorporates an internal flame relay with a fixed ON/OFF threshold thereby eliminating the need for an external flame amplifier.
Key Features
- Self-Checking Design: Electro-mechanical shutter mechanism provides proof-of-operation diagnostics
- Internal Flame Relay: Fixed ON/OFF threshold eliminates need for external amplifier
- UV-Eye Detector: Uses a UV-eye detector—a sealed, gas-filled, UV-sensitive tube containing two electrodes connected to a DC voltage source.
- Microprocessor-Based: Provides reliable flame signal processing and monitoring
- Industrial Rating: NEMA 4x / IP66 rating suitable for use in Class I Division II, Group A, B, C, & D hazardous environments.
- Status Indication: Two-color internal LED indicates flame status (off/on) and alarm condition.
