Compared with traditional sensors, distributed fiber temperature measurement systems have natural advantages, including:

(1) Continuous distributed measurement

The distributed optical fiber sensor is a truly distributed measurement, which can continuously obtain the measurement information along the detection cable tens of kilometers, and the false positive and false negative rate are greatly reduced. Real-time monitoring is also realized.

Lightning often destroys a large number of electrical sensors. Optical fiber sensors can resist the impact of high voltage and high current due to their complete electrical insulation.

The two outstanding advantages of optical fiber are the large amount of data transmission and small loss, and the remote monitoring of tens of kilometers can be achieved without relaying.

In theory, the sensitivity and measurement accuracy of most optical fiber sensors are better than that of general sensors, and the actual mature products have also proved this.

The material of optical fiber is generally quartz glass, which has the characteristics of non-corrosion, fire resistance, water resistance and long life, and can usually serve for 20 years. Considering the sensor's own cost and later maintenance costs, the use of optical fiber sensors can greatly reduce the final operating costs of the entire project.

(2) Anti-electromagnetic interference, can work normally in a high electromagnetic environment

The fiber itself is composed of quartz material, completely electrically insulated; At the same time, the signal of the optical fiber sensor is based on the optical fiber as the carrier, which is inherently safe and is not interfered by any external electromagnetic environment.

(3) Intrinsic lightning protection

(4) The measurement distance is far, suitable for remote monitoring

(5) High sensitivity, high measurement accuracy

(6) Long life, low cost, simple system
