1、Composition of fiber optic thermometer
The fluorescence fiber thermometer consists of three parts: a fiber optic transmission line with a fluorescence fiber optic probe, a fiber optic modem, and a fiber optic communication converter. The thermometer used in the fluorescence fiber thermometer system is a 6-channel fluorescence fiber thermometer host. The principle and method of six channel temperature measurement are completely the same, and temperature collection and monitoring will be carried out in a circular manner according to certain principles.
2、The principle of fiber optic temperature measurement device
Firstly, 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.
