Distributed fiber optic temperature measurement is the best method for cable temperature measurement

Characteristics of Distributed Fiber Optic Temperature Measurement System
(1) Non electric measurement technology

In the past, manual and electronic measurements were often used for parameter measurement in some hazardous situations. Distributed fiber optic temperature measurement technology has innovated and adopted on-site non electric measurement technology, achieving true intrinsic safety.

(2) Fast response speed, complete machine response time:<2 seconds, this indicator is the most important technical indicator of the fiber optic distributed temperature monitoring system. Fast response speed, fast system signal acquisition speed, fast alarm speed, completely eliminate safety hazards caused by long alarm cycles. The new generation of high-speed signal processors represents the highest level in China, with a response speed of 2 seconds for instruments.

(3) It can achieve single point temperature measurement, positioning, and point by point alarm in case of faults. When an alarm occurs, it can not only output signals in different zones, but also accurately locate the distributed detection fiber optic position. The positioning accuracy is less than 1 meter, which is conducive to the accurate execution of fire protection work and maintenance. The temperature of each detector can be clearly detected.

(4) Distributed continuous fiber optic temperature measurement has extremely high accuracy in China. In the past, distributed fiber optic temperature measurement applications generally achieved an accuracy of 3 ℃ -5 ℃. After using certain software and hardware technologies in the system, the accuracy can be improved to 1 ℃, making the system more reliable and applicable for measurement.

(5) The technological advantage of sensors is that the distributed fiber optic temperature measurement system uses an all fiber passive component, which has incomparable advantages and characteristics compared to ordinary sensors. It is inherently explosion-proof, non electric sensing, chemically stable, has a long transmission distance, and can be used for absolute measurement of external parameters. This characteristic has aroused great interest in the field of sensors. Becoming a hot topic in the field of sensing research. Distributed fiber optic sensing technology represents the development trend of the new generation of sensing technology. Its industry has been recognized as one of the most promising high-tech industries both domestically and internationally. It has attracted worldwide attention for its high technological content, good economic benefits, strong penetration ability, and broad market prospects.

(6) A solution to safety monitoring: Safety monitoring focuses on addressing the hidden dangers in current heating pipelines, with a focus on solving the fiber optic distributed temperature monitoring and warning system for pipelines.

(7) Data can be transmitted to the temperature measurement host for sound, light, and SMS alarms, achieving linkage with fire protection.
