Characteristics manual of distributed fiber optic temperature measurement system

Distributed fiber optic temperature measurement systemThe distributed fiber optic temperature sensing system adopts advanced OTDR temperature measurement technology to achieve temperature monitoring and positioning along the fiber optic line. It is a real-time, online, and continuous temperature measurement system. The distributed fiber optic temperature measurement system can accurately monitor the specific temperature of the measured object at the temperature point. The fiber optic temperature system has advantages such as real-time online reaction speed, accurate temperature measurement accuracy, intrinsic safety of the fiber optic, and no strong electromagnetic interference. It can be widely used in different occasions such as power cables, petrochemicals, rail transit, industrial metallurgy, etc. Real time online monitoring of the temperature situation of the measured object during operation will not cause faults and fire accidents due to temperature rise, and can achieve no equipment damage and accidents caused by temperature faults.

The linear fiber optic temperature fire detector developed based on the principle of DTS distributed fiber optic temperature sensor technology is a widely used system in fire and firefighting in China. The main principle is to use fiber Raman scattering technology, combined with advanced fiber optic technologies such as high-frequency pulse laser, optical wavelength division multiplexing, optical time-domain reflection, high-frequency signal acquisition, and weak signal processing. The distributed fiber optic temperature measurement system can also be used for large-scale fiber optic temperature measurement in power cables, pipeline tunnels, petroleum gas tanks, and other areas. Due to the inherent safety characteristics of optical fibers, distributed optical fiber fire temperature sensing systems are more suitable for fire detection in hazardous areas such as flammable and explosive, as well as industrial fire protection projects with strong electromagnetic interference, corrosion, high temperature, and explosion-proof requirements. Distributed fiber optic mainly consists of fiber optic hosts and detection fiber optic cables. Among them, the fiber optic host is responsible for fiber optic signal processing, alarms, and parameter settings, while the detection fiber optic cable is responsible for on-site temperature collection. The fiber optic host can also be connected via RS485/232 CAN、 The Ethernet interface is connected to the fire alarm controller to form a complete fire alarm system.

Distributed Fiber Optic Temperature Measurement Manual

The distributed fiber optic temperature sensing system consists of a fiber optic temperature measurement host, temperature sensing fiber optic, system management software, and related accessories, using Raman scattering OTDR technology enables temperature monitoring and positioning. It can continuously obtain measurement information along the detection optical cable for tens of kilometers, with low false alarm and false alarm rates, and can achieve real-time monitoring. Ultra low power consumption, low host power consumption, cleverly designed. Fiber optic is resistant to electromagnetic interference and does not affect operation in high electromagnetic environments. Long measurement distance, suitable for remote monitoring. It can be customized with GPRS SMS alarm function, without the need for manual monitoring. The temperature measurement system supports multiple fire alarm methods, including early warning, differential temperature, and fixed temperature. Alarm zones and alarm temperatures can be set arbitrarily. Distributed fiber optic hosts have a long lifespan, reasonable prices, and complete systems with high-quality after-sales service.
