Self-resetting sensibilization type pressure monitoring device based on fiber bragg grating

The utility model provides a self-resetting sensitization type sensing monitoring device based on a fiber bragg grating, which belongs to the technical field of pressure monitoring and comprises a main shell, a pressure bearing mechanism, a force transmission mechanism and a fiber bragg grating sensor. The pressure-bearing mechanism is arranged at the upper part of the main shell; the force transmission mechanism is arranged at the lower part of the main shell; and the fiber grating sensor is arranged at the bottom of the main shell, and the wavelength of the fiber grating sensor is changed through pushing of the push rod. According to the self-resetting sensibilization type pressure monitoring device based on the fiber bragg grating, tiny pressure can be accurately detected by utilizing the wavelength change of the fiber bragg grating sensor, and the change of a pressure bearing value can be quickly sensed. The micro pressure sensor is light and handy in structure, can amplify, monitor and analyze micro pres
