Distributed Temperature Sensing (DTS)
Introduction
Distributed optical fiber linear Temperature detector is a differential constant temperature fire detector with independent intellectual property rights developed by the company, which adopts continuous Distributed Temperature Sensing System (DTS). Advanced OTDR technology and Raman scattered light are used to detect temperature changes along different positions of the fiber, which can not only predict the fire stably and accurately, but also accurately locate the location of the fire.
