1 overview
HZHT 32 ex - 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 manufacturing of an ultraviolet light type furnace flame detection device. It has a simple structure, convenient operation, reliable performance, etc. It can be a long-term continuous detection of various gas boiler flame, and can be used in with the use of natural gas, coal gas and other gas or other media and may produce explosive gas environment. A variety of essential safety monitor system for gas boiler inspection equipment, specially developed for petrochemical production thermal monitoring explosion-proof products.
2 the structure and working principle
Explosion-proof flame detector is the front of the UV light tubes containing quartz dust before the lens,
