Characteristics and parameters of distributed fiber optic temperature monitoring system

Fiber optic temperature measurement is a reliable temperature measurement method that can be used for various power equipment. Compared with other temperature measurement methods, it has the characteristics of fiber optic sensor insulation, high voltage resistance, and anti-interference. INNO fiber optic temperature measurement technology is leading in China and is reasonably priced.

The distributed system fiber optic temperature monitoring system software is a real-time, online, and continuous online temperature monitoring system software. It has the advantages of real-time online, high temperature measurement accuracy, basic safety factor, and no interference signal.
The distributed system fiber optic temperature measurement system is a new generation distributed system fiber optic temperature detection server developed and designed based on fiber optic electronic optics, optoelectronics, small signal analysis technology, and high-speed data signal collection and resolution technology. It uses embedded hardware and software system software components. The fiber optic temperature detection server accurately measures a long distance (16km), has a fast response time (2s), and a high measurement accuracy (0.5c). Its important performance indicators are leading, and it has advantages such as system software reliability, compact structure, and poor power. Customers can select the corresponding physical model according to the program operation regulations.

Characteristics of Distributed Fiber Optic Temperature Measurement System

1. The key components use military grade semiconductor materials such as laser generators, photodetectors, and fiber filters, which have stable characteristics, complete technical requirements, high cost to cost ratios, and credibility and reliability for on-site industrial production;

2. Using a computer to adjust the amplitude value of the initial optical signal and maintain the gain value in an automatic control system. The credibility and precision of the system software have been further improved.

3. By using a long wavelength laser generator and related semiconductor materials, the optical signal loss in temperature sensitive fibers is small, and the precise measurement distance can reach over 4 kilometers.

4. The slope of the straight line is mainly used for parameter correction, obstruction, and secondary index correction. The controller is used to test the optical fiber for more accurate testing, which is very important for the application of large temperature changes. And can integrate various unique optical fibers.

5. Choose modular design server construction to drive technological and system upgrades.

6. Choosing a new signal analysis method prevents the hassle of saving the background graph curve, making the application more convenient and reliable;

7. Using RS232 communication method to present communication protocol and promote the secondary development trend of customers, in order to consider the personal requirements of different customers;
