Description

technical field [0001] The invention relates to an optical fiber sensing device, in particular to a high temperature resistant and heavy load optical fiber sensing device. Background technique [0002] In the process of smelting steel, it is necessary to weigh the molten steel in the ladle. Since the temperature of the molten steel is more than 1600 degrees and the weight of the ladle is between 100 and 500 tons, the temperature and weight have a great influence on the weighing sensor device. There is even molten steel splashing, which all put forward higher requirements for the load sensing device, so that the existing sensing device based on the principle of resistance strain cannot be durable, thereby causing hidden dangers in ensuring safe production and improving product quality. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a high-temperature-resistant and heavy-load...
