High-frequency dynamic pressure measuring device

Abstract

The invention discloses a high-frequency dynamic pressure measuring device. The high-frequency dynamic pressure measuring device comprises a sealing device and an elastic element; the sealing device comprises a sealing component and a sealing cover plate; the central part of the bottom of the sealing component is provided with a connector; the interior of the connector is of a hollow structure; the elastic element comprises a body and a fixing base; the body is a cylinder; a groove is formed in one bottom surface of the body; the fixing base comprises a base, a supporting seat and a fixing cylinder; the supporting seat is arranged on the base; the fixing cylinder is arranged on the supporting seat; and the area of the bottom of the fixing cylinder is slightly smaller than the area of the bottom of the groove of the elastic member; the fixing cylinder is embedded into the groove; and the elastic member is embedded into the hollow structure. According to the high-frequency dynamic pressure measuring device of the present invention, the elastic element is built into the connector of the sealing component, so that a pressure transmission distance can be the shortest, and therefore, a high-frequency response effect can be achieved, and an ideal dynamic pressure measurement result can be obtained.

Description

technical field [0001] The invention relates to a high frequency response dynamic pressure measuring device. Background technique [0002] In pressure measurement systems, there are generally two forms of pressure measurement, namely static pressure measurement and dynamic pressure measurement. In a static pressure system, the change of pressure is often not too drastic, the dependence of pressure on time is not strong, and the requirements for frequency response are often not high. Such as tap water pressure monitoring system. However, in a dynamic pressure system, the pressure changes are often very drastic, and the application has high requirements on the frequency response of the measurement system. Such as the cylinder pressure of the engine, the pressure of the shell when it is fired, etc. This kind of pressure is often explosive and even fleeting. To accurately measure such pressure is a great test for the measurement system. However, many control methods must kno...

Problems solved by technology

However, many control methods must know the current pressure (strong) force more accurately, and the time delay for dynamic pressure measurement should be as short as possible.
