Abstract

The invention discloses a gas pressure measuring device. The housing is connected up and down, and internal threads are arranged at the upper and lower openings. A lower support block is cylindrical and is provided with external threads on the outer periphery. It is connected with the lower end of the shell; the support base is placed on the upper surface of the lower support block, and a through hole is provided on the support base, and the strain gauge is placed on the upper surface of the support base, at the position of the side wall of the shell relative to the strain gauge A small hole is opened, and a flexible transmission line is connected to the strain gauge, and the flexible transmission line protrudes from the small hole, and a flexible medium is placed on the upper surface of the strain gauge. The invention has the advantages of good measurement effect by using the strain gauge, and the control circuit is removed from the measurement device, ensuring the safety of the measurement device, simple structure, good measurement effect, easy operation, and easy popularization and use.

Description

technical field [0001] The invention belongs to the technical field of pressure measurement, and in particular relates to a gas pressure measurement device. Background technique [0002] In actual production and life, it is often necessary to measure the pressure of gas, and pressure gauges are pre-installed on the equipment of large enterprises. When it is necessary to measure gas pressure temporarily, there is often a lack of corresponding devices. The existing pressure measurement device for gas pressure measurement includes: a control circuit board, a pressure sensor arranged on the same side surface of the control circuit board, and an application-specific integrated circuit matched with the pressure sensor. In order to improve the sensing sensitivity of the pressure sensor, the area of ​​the pressure sensing surface of the pressure sensor and the surface opposite to the pressure sensing surface is larger than the side surface, and when the sensor is packaged, the surfa...
