DISTRIBUTED OPTICAL FIBER TEMPERATURE MEASUREMENT HOST

New Products / New Technology

In the field of fire protection, this product is defined as a "distributed optical fiber line temperature sensing fire detector" according to the GB16280-2014 national standard. The DTS host is responsible for the processing of optical sensing data. In engineering practice, the DTS system needs to use sensing optical fibers to monitor the temperature of the environment where the optical fibers are located in real time. It is suitable for early warning of small hot spots such as electric power, petrochemical, coal mine, fire protection, pipeline leakage, temperature monitoring of belt conveyor bearings, and early warning of thermal runaway inside lithium batteries. It has a 7-inch touch screen operation UI interface, which can be convenient for local operation without installing software, and integrates the functions of automatic calibration of optical fiber temperature and one-key automatic parameter adjustment

DISTRIBUTED OPTICAL FIBER ACOUSTIC VIBRATION DAS HOST

Pure phase sound vibration reduction mode demodulation; 20-60km monitoring length; Positioning accuracy 2-10 meters adjustable; Distributed measurement can be linked with third-party systems; It can be connected to various third-party security monitoring systems. The system has strong anti-interference ability: it is not interfered by electromagnetic or various rays, and has good concealment; The sensing system is a distributed measurement, every 2.5 meters on the optical fiber is equivalent to an acoustic vibration sensor, and the system uses the sensing optical cable as the front-end detector to prevent interference from metal and ground wires; The system uses sensing optical cable as the front-end detector and has strong anti-corrosion ability; The outdoor part of the system adopts passive design, which is intrinsically safe.

DISTRIBUTED FIBER OPTIC STRAIN SENSING BOTDA HOST

The distributed optical fiber temperature strain sensing system, which adopts the optical fiber Brillouin backscatter effect and the optical time domain reflection OTDR principle, is the latest generation of distributed optical fiber sensors in the world, which can realize the temperature, strain and spectrum measurement of each point along the ultra-long-distance optical fiber, with a measurement distance of up to 120km, a measurement accuracy of 1C/20με, and a measurement time of less than 60s. The use of standard communication single-mode optical fiber as a sensor, "transmission" and "sensing" in one, can monitor subtle temperature and strain changes in real time, and has important applications in long-distance oil and gas pipelines, submarine photoelectric composite cables, power overhead lines, dams, bridges and other fields.
