Dt-f100 comprehensive load monitoring system is to fix the fiber Bragg grating on the tensile elastic matrix, obtain the elastic matrix strain sensor through the fiber Bragg grating measurement, and then get the tensile force of the elastic matrix, which has compact structure, high measurement accuracy and strong anti deflection ability. This type of special tension sensor for high-voltage line tower is generally installed between insulator string and cross beam of the tower to measure the comprehensive load of the conductor. The sensor can also be used in other tension monitoring occasions. A fiber Bragg grating temperature sensor is installed inside the sensor to compensate the temperature effect on the measurement.

Advantages of the system:

1、High precision, stability and reliability
2、Intrinsically safe, not subject to electromagnetic interference, anti-corrosion, anti pollution, strong anti lightning ability, can be used in strong electromagnetic interference, high lightning, flammable, explosive and other harsh conditions
3、The transmission distance of sensor signal is far, up to 40km
4、Quasi distributed measurement, multiple sensors can be connected in parallel on one optical fiber (typical: 6)
5、A fiber Bragg grating temperature sensor is installed inside to compensate for the influence caused by temperature change
6、Simple layout, can be mixed with other types of FBG sensors
