This Honeywell Ultra-Violet Amplifier is a specialized device designed to detect the presence of a flame in combustion systems. It operates with a response time of 3 seconds, providing rapid feedback for system control. The amplifier works by sensing ultraviolet radiation emitted by the flame and amplifying this signal for interpretation by the control system. It is compatible with Honeywell's R7847, R7848, R7849, and R7851 Flame Detectors, as well as their R7861 Flame Amplifiers. This product is designed for use in industrial applications where reliable flame detection is critical for safe and efficient operation.
