Overview

Distributed fiber optic temperature warning system is a kind of high-tech products which is used for real-time measurement of spatial temperature distribution. It not only has the advantage of ordinary optical fiber sensor, but it also has distributed temperature sensing capacity for various points along the fiber. Fiber is both a conductor for transmission of information and sensors for distributed measurement. It can continuously measure the temperature along the fiber, the spatially positioning accuracy can reach the order of 1m within 30 kilometers. It is particularly useful for applications which need large-scale multi-point measurement.

        Distributed fiber optic temperature warning system has advantages such as high precision, high data transmission speed and read speed, good adaptive performance, easy installation and maintenance, etc. Beijing Oriental RayZer Technology Ltd. take advantages of the domestic and foreign researches, combined with advanced semiconductor laser technology, fiber optic filtering techniques, high-speed photoelectric conversion and signal acquisition technology, large-scale digital circuits and advanced computer technology, we have developed a distributed optical fiber temperature warning system. The performance of the system reached the international advanced level. Its excellent performance and reasonable price will bring great convenience and efficiency to the safety monitoring of a variety of complex work site. The fiber which the system uses is not charged, anti-radio frequency and electromagnetic interference, flame and explosion proof, corrosion resisitant, can withstand high temperature and strong electromagnetic fields, anti-electromagnetic radiation, long-term operation in hazardous environment. Laying a few kilometers, even tens of kilometers of optical fiber (fiber are both transmission media and sensing media) across the test space, the system can realize continuous measurement and accurate positioning of all the points and its temperature in the entire space. Through the optical fiber temperature changes, we can obtain the changes of the environment, as a result, the system is widely used in many fields which require long-term and real-time security monitoring, such as defense and military, petrochemical and civilian, etc.

Product performance and technical parameters

Distributed fiber optic temperature measurement warning system contains two parts: the temperature host and probe cable:

1、 Temperature host and its characteristics

2、Probe cable

ORZ-DTS-OC01 probe cable is a multi-mode fiber optic cable. The fiber adopt thixotropic aramid fibers used for protection. The fiber jacket uses high performance flame retardant PVC material. The fiber is well sealed in order to ensure that it won’t be affected or damaged by the outside environment. At the same time, the optical fiber cable has excellent thermal conductivity, mechanical properties, water proof and corrosion resistant properties, and it can be used in harsh environments for a long time. We can customize probe cable according to users’ requirements.
