Distributed optical fiber sensing fire detector

HG-DTS series distributed optical fiber temperature sensing system is composed of optical fiber temperature sensing host, temperature sensing optical fiber, system management software and related accessories. Raman scattering and OTDR technology are used to monitor and locate temperature.

Product function

1. distributed temperature detection, high temperature accuracy and accurate positioning, to provide reliable and accurate data for customers;

2.24 hours real-time online monitoring, over temperature warning, truly unattended.

3. alarm threshold, management partition, alarm operation and other software can be set up and operate conveniently.

4. field optical fiber damage identification and accurate positioning, convenient maintenance;

5. overheat alarm does not damage the temperature sensitive optical fiber, which can be reused and reduce maintenance costs.
