Overview
The Eclipse 49600-91 is a professional-grade ultraviolet (UV) flame scanner engineered for continuous monitoring of gas and oil flames in industrial burner systems. This sensor features high sensitivity ultraviolet (U.V.) for monitoring gas or oil flames which cycle on and off frequently. The Eclipse flame safeguard checks for a short-circuited, or “run-away” scanner at the beginning and end of each flame cycle. The 49600-91 is UL listed, CSA certified and FM approved, meeting rigorous safety standards for combustion control applications.
Key Features
- UV Detection Technology: The SB49600-91 features advanced UV sensor technology that detects UV radiation emitted by combustion flames, providing quick and precise flame detection.
- Run-Away Scanner Protection: Built-in safety logic detects short-circuited or malfunctioning scanners automatically.
- High-Temperature Rated: The scanner body does not exceed 257°F (125°C) from conducted, radiated, or ambient heat.
- Pre-Assembled Cable: It comes with a 6 foot cable lead with insulated coupling for convenient field installation.
- Compact Aluminum Housing: Durable, flame-resistant construction rated for industrial combustion environments.
