1 overview
HZHT - 31 type flame detector is according to the ministry of relevant standards and norms, summarize and absorb the experience of similar products at home and abroad, using UV detection technology design and manufacture of a new type of UV type furnace flame detector. It has a simple structure, convenient operation, reliable performance, etc. It can be a long-term continuous detection of various gas boiler flame, and is an essential part of a variety of gas boiler safety monitoring system of testing equipment.
2 the structure and working principle
HZHT - 31 flame detector consists of two parts, processor and probe. Between the processor and the probe consists of two core twisted-pair cable connection.
HZHT - 31 of flame detector probe before UV light at the end of the tube fitted with quartz dust lens, the light transmit the signals to probe the tail flame UV light pipe, ? done by UV light tube light
