Abstract

The invention relates to a hair temperature and humidity sensor based on optical fiber Bragg gratings and a using method thereof, and belongs to the technical field of photoelectron measurement. The hair temperature and humidity sensor comprises an adjusting screw, a support, fixing screws, the optical fiber Bragg gratings, an equal-strength cantilever beam, a hair bundle, a hair hook and connecting bodies, wherein the fixed end of the equal-strength cantilever beam is fixed on the inner side of the support through the fixing screws, the free end of the equal-strength cantilever beam is connected with one end of the hair bundle through one connecting body, the other end of the hair bundle is fixed on the hair hook through the other connecting body, the hair hook and a base of the support are integrated, the adjusting screw arranged at the bottom of the support is used for adjusting stress of the hair bundle, and the optical fiber Bragg gratings of the same model number are pasted on the symmetry central line of the upper surface and the lower surface of the equal-strength cantilever beam and are connected with a signal processing device. By means of the sensor, temperature and humidity can be measured at the same time, the anti-interference ability is strong, and intrinsic safety is good.

Description

technical field [0001] The invention relates to a hair temperature and humidity sensor based on an optical fiber Bragg grating and an application method thereof, belonging to the technical field of optoelectronic measurement. Background technique [0002] The degree of dryness and humidity of the environment is called "humidity". Industries such as aerospace, power generation and transformation, textiles, food, medicine, and storage have very strict requirements on humidity. Effective real-time monitoring and control of humidity parameters is the key to normal production and life. premise. Humidity is often measured by physical quantities such as absolute humidity and relative humidity. Absolute humidity is the mass of water vapor contained in a certain volume of air, and its limit is the highest humidity in a saturated state. Absolute humidity is inversely proportional to thermodynamic temperature; relative humidity is the ratio of absolute humidity to the highest humidity...
