Pressure measurement sensitive component

Abstract

The invention relates to the related technical field of pressure detection equipment, in particular to a pressure measurement sensitive component, which is characterized in that a sealing piece is fixedly mounted on the upper end surface of a protective shell; a pressure head is fixedly mounted on the upper end surface of the sealing sheet; a sealing groove is formed in the upper surface of the protective shell; a glue injection groove is formed in the lower bottom surface of the protective shell; through holes are formed in the bottom of the sealing groove at intervals in a penetrating manner; a liquid inlet hole is further formed in the bottom of the sealing groove in a penetrating mode; a steel ball is arranged at the liquid inlet end of the liquid inlet hole; a ceramic pad is mounted in the sealing groove; sintered glass is fixedly mounted in the through hole; a mounting cavity is formed in the upper surface of the ceramic pad; a sensing chip is embedded in the inner bottom surface of the mounting cavity; wire guide holes are formed in the bottom surface of the mounting cavity at intervals in a penetrating manner; a lead is mounted in the sintered glass in a penetrating manner; and the pressure measurement sensitive assembly is reasonable and compact in overall structure, small in installation occupied space, good in sealing performance and high in expansibility.

Description

technical field [0001] The invention belongs to the related technical field of pressure detection equipment, and in particular relates to a pressure measurement sensitive component. Background technique [0002] At present, the hydraulic system and gas system inside the aviation equipment need to measure a lot of pressure values. The internal components of the aviation equipment are usually relatively precise and small, so some pressure sensing test devices with relatively small volume must be used for pressure detection. The internal chip transmits the pressure signal to the external display device through the wire, and the staff can clearly understand the pressure value through the external display device. The equipment in the existing industry is usually relatively large in size, which will cause the equipment to take up more space during installation; the equipment in the industry can usually only install a single pressure sensor chip, which will cause the equipment to o...
