This Honeywell Ultraviolet Scanner is a robust and reliable device designed to detect the ultraviolet radiation emitted by combustion flames. The scanner features a self-checking mechanism that ensures its functionality and accuracy, providing continuous monitoring of the flame's presence in heating equipment like boilers, furnaces, and ovens. It operates effectively under extreme conditions, thanks to its explosion-proof (XPROOF) housing that protects it from volatile environments. The device uses ultraviolet (UV) sensing technology, which is highly sensitive to UV radiation and less likely to be affected by visible light or infrared radiation. This makes it suitable for applications where other types of flame detectors may fail due to interference. The product is compatible with Honeywell flame safeguard controls, allowing for seamless integration into existing systems.
