BWYF - GXCW - DC intelligent fluorescent reflection type optical fiber temperature sensor, according to the actual application process of the specific situation, through the concentration of research and a lot of experiments, from the principle and structure of the sensor probe and directional coupler innovation and improvement of the successful development of new products. The sensor probe uses the principle of composite reflection not only to achieve a greater range of linearity, and the structure is more simple and firm, to achieve the miniaturization, installation is more convenient. Directional coupler structure more compact, more stable work, directional coupling degree increased by more than 15dB, so that the system sensitivity and reliability greatly improved.

BWYF GXCW optical fiber temperature measurement monitoring device, for our company's intelligent optical fiber temperature measurement data monitoring and display device, with 4 485 bus interface, each interface can take 10 optical fiber temperature sensors. Multi-channel dry contact alarm output function. The panel includes touch screen display, ship switch, etc.

The software platform adopts the small kernel operating system designed by ourselves for the device platform. Because it is customized, it shows the characteristics of high efficiency and stable operation, and fully ensures the high reliability of the software system.
