Rack-mounted distributed optical fiber linear temperature fire detector

Introduction

The distributed optical fiber linear temperature fire detector consists of a sensitive component and a signal processing unit connected to it. The sensitive component of the distributed optical fiber linear temperature fire detector is a temperature-sensitive optical fiber, which transmits the signal to the signal processing unit (distributed optical fiber temperature measurement host) through the temperature-sensitive optical fiber, which can achieve temperature measurement and positioning within a long distance.

4 channels, 2.5km per channel/2 channels, 5km per channel, positioning accuracy 1m, temperature resolution up to 0.8℃, and has a series of alarm functions such as temperature threshold, temperature change rate and temperature peak, fiber break alarm, etc.

Implementation standards GB16280-2014, Q/XSSEL 019-2020, GB 3836.1-2010, GB3836.4-2010, GB3836.20-2010.
