JTW-XD-9624 Fiber Bragg Grating Temperature Measurement System
JTW-XD-9624 linear fiber optic temperature fire detector is produced by Xi'an Shengsaier Electronic Co., Ltd. Co., Ltd., it uses optical fiber as the signal transmission and sensing medium, using Bragg The temperature sensitivity of the grating and the reflection principle of light can detect the temperature sensing along the fiber grating in real time. Point temperature changes, can sound and light alarm when exceeding the limit.
The product has high detection sensitivity; Distributed measurement, measurement points can be set arbitrarily within 5km; on-site non-electric detection, essential Safety explosion-proof, anti-electromagnetic interference, anti-lightning strike. Especially suitable for traffic tunnels, oil and gas pipelines Road, chemical industry, metallurgy, electric power, fire protection, energy, storage, military industry, nuclear industry and other places. Book The system conforms to the relevant provisions of GB3836.1-2000 and GB3836.4-2000 standards, The national explosion-proof electrical product quality supervision and inspection center passed the inspection and obtained the explosion-proof certificate. Product by The National Fire Electronic Product Quality Supervision and Inspection Center has passed the inspection. It is suitable for Zone 0, Zone Ⅰ, Zone Ⅱ Areas containing explosive gas mixtures of Groups T1-T6 of Class II A-II C.
