2、O princípio de dispositivo de medição de temperatura de fibra óptica

Primeiramente, fix one end of the fiber optic transmission line with a fluorescent fiber probe at the test point, and connect the other end to the fixed connection point with a laser in the modem. Connect the modem and RS232-485 converter, connect 220V AC power to the modem, and the fluorescence fiber thermometer will start working. The laser emits a fixed wavelength of light excitation, which is transmitted through a fiber optic transmission line to excite the fluorescent substance inside the probe. The fluorescent substance emits corresponding fluorescent afterglow. After the light excitation is cancelled, the fluorescence afterglow is transmitted to the photodetector through the filter in the modem, and then the temperature signal is transmitted to the upper communication system through the converter.
