Description

technical field [0001] The invention relates to pressure measuring technology, in particular to a pressure measuring instrument. Background technique [0002] Pressure measurement is of great significance to real-time monitoring and safe production. In oil extraction, in order to produce efficiently and safely, it is necessary to effectively control various conditions in the production process. Since pressure control plays a decisive role in the production process, accurate measurement Pressure is even more important. In order to meet the needs of the industrial field, the existing pressure measuring devices generally have a complex structure, high cost, and no industry versatility, which makes it difficult to popularize and apply in the civilian field. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a pressure measuring instrument, which has a simple overall structure, is easy to implem...
