Embodiment Construction

[0012] A miniature capacitive sensor and an integrated electronic pressure gauge with a pressure-bearing structure, including a cylindrical movable plate 1 made of elastic metal material as a casing, and fixed to the cylindrical movable plate 1 through end caps 2 and 3 In the center, the cylindrical fixed pole plate 4 that forms a detection capacitance with the cylindrical movable pole plate 1 is provided with the detection capacitance formed by the cylindrical fixed pole plate 4 and the cylindrical movable pole plate 1 in the cylindrical fixed pole plate 4. The output terminal is connected to the measuring circuit 5. Both ends of the cylindrical movable plate 1 are covered with inherent breech rings 6, 7. The elastic metal material adopts martensitic effective steel, and the yield limit stress of this material is: σ s =2000Mpa. In fact, all metal materials are elastic materials, but their elastic ranges are different. For example, some metals undergo plastic deformation at ...

Abstract

The invention relates to an electronic pressure gauge for pressure measurement, in particular to an electronic pressure gauge integrated with micro capacitance sensor and bearing structure. The pressure gauge solves the problem that pressure sensors of the current electronic pressure gauges have quite large size, so that the overall size of the electronic pressure gauges are too large, and the pressure gauges cannot be used in occasions with limited space. The electronic pressure gauge integrated with micro capacitance sensor and bearing structure includes a cylindrical dynamic plate made of elastic metal material and as a shell, and a cylindrical fixed plate which is fixed in the center of the cylindrical dynamic plate and forms a detection capacitance with the cylindrical dynamic plate; a measuring circuit connected with the output of the detection capacitance consisting of the cylindrical fixed plate and the cylindrical dynamic plate is arranged in the cylindrical fixed plate. The invention has the advantages of simple structure, small size, wide scope of application, low manufacturing cost, etc.

Description

technical field [0001] The invention relates to an electronic pressure measuring device for pressure testing, in particular to an electronic pressure measuring device integrated with a miniature capacitive sensor and a pressure bearing structure. Background technique [0002] The electronic pressure gauge is a special test instrument suitable for the gun bore pressure test. It is suitable for putting in the pressure test equipment for the transient pressure test in the special environment of high temperature and high pressure in the gun bore. According to the particularity of its use environment, the electronic The pressure gauge has the following requirements: 1. It can withstand the high pressure in the chamber and the instantaneous high temperature accompanying the high pressure. The high pressure can reach 800MPa, and the instantaneous high temperature can reach 3000°C. Therefore, the environmental adaptability of the electronic pressure gauge is very high. ;2. The elect...
