Fiber optic temperature measurement products mainly use sensing fibers for temperature measurement and monitoring, with advantages such as high accuracy, no electromagnetic interference, and real-time online. If this type of fiber optic cable is emitted to explosive hazardous areas, the possibility of explosion caused by light radiation must be considered, and explosion-proof certification must also be considered.
The implementation standards for explosion-proof certification of fiber optic temperature measurement products are GB/T 3836.1 and GB/T 3836.22, mainly considering the product's circuit and the emission power of the laser generator.
Shenzhen Zhongnuo Testing has successfully obtained multiple explosion-proof certificates and coal safety certifications for customers in the field of fiber optic temperature measurement hosts, accumulating rich experience in evidence collection. We can provide customers with consulting services such as explosion-proof product design rectification, drawing guidance, and evidence collection. If you have any certification needs in this area, remember to send us a private message!
