1. Overview

XHT-3 Ultraviolet Flame Detection Device is an intelligent flame detection device designed and manufactured in accordance with gas safety standards and specifications. It consists of a probe and a signal processor, and the probe and processor are connected by two core twisted pair shielded cables.

2. Working principle

The light signal emitted by the flame is transmitted to the UV photosensitive tube at the tail of the probe, and the photoelectric conversion is completed by the UV photosensitive tube. The signal transmission between the probe and the processor adopts the current transmission method to improve the anti-interference ability, and is transmitted to the processor through a shielded cable. After the electrical signal is processed by the processor, it outputs a fire or no fire signal in the form of a switching value.
