Abstract

The invention relates to a high-temperature and pressure kettle which is used in optical fibre sensor, it includes a high-pressure autoclave which is in calorstat, a high-pressure metering pump is mounted out of the calorstat, the high-pressure metering pump is connected with high-pressure autoclave via hollow tube, the optical fibre sensor is mounted in the high-pressure autoclave; the hollow tube connected with the optical fibre sensor is also mounted in the high-pressure autoclave, the hollow tube is connected with the outer of the calorstat, the fibre connected with the optical fibre sensor is lead to the outer of the calorstat via the hollow tube. The fibre between several optical fibre sensors is covered with hollow tube; optical fibre ring flange high-pressure protecting house is mounted in the hollow tube. The invention can measure and calibrate the optical fibre sensor in different temperature and pressure safely, test the temperature parameter or pressure parameter of optical fibre temperature or pressure sensor, two- parameter testing can also be done. It is safe, structure is simple, easy to mount and demount.

Description

technical field [0001] The invention relates to a high-temperature autoclave experimental device for optical fiber sensors, in particular to a high-temperature autoclave experimental device capable of measuring temperature and pressure dual parameters of optical fiber temperature and pressure sensors. Background technique [0002] As we all know, fiber optic sensors, especially fiber Bragg grating temperature and pressure sensors, have many unique advantages, so they are more and more concerned and valued by users. However, the laboratory measurement and calibration of fiber optic temperature and pressure sensors has always been a difficult problem for people in the industry. [0003] At present, the commonly used methods for applying pressure to the optical fiber temperature and pressure sensor are: the pressure to be measured is obtained from the gas pressure in the oxygen cylinder. (Liu Yunqi, Zheng Jiancheng, Liu Zhiguo, etc., "Pressure and temperature characteristics o...
