Problems solved by technology

[0003] After the existing pressure sensor is installed, it can only detect the pressure of one device. For the pressure of different devices, it is necessary to disassemble the pressure sensor and then install it, and then detect it, or install a pressure sensor for each device that needs to be detected. This method is not only time-consuming and labor-intensive, which reduces the detection efficiency, but also increases the use of a large number of pressure sensors, which cannot make rational use of resources. At the same time, it also increases the workload of installers and testers.

Abstract

The invention discloses a pressure sensor with a double-air-inlet-pipe structure, which belongs to the technical field of sensors and solves the problem that after an existing sensor is installed, only the pressure of one device can be detected, and the efficiency is low. The pressure sensor is technically characterized by comprising a shell; a cylindrical groove is formed in shell;a silicon ringis arranged at the bottom of the cylindrical groove; a silicon diaphragm is arranged at the bottom of the silicon ring; the interior of the shell is divided into a high-pressure cavity and a low-pressure cavity through thesilicon diaphragm; a left inlet is formed in the left side of the shell; a right inlet is formed in the top right side of the shell; the left inlet and the right inlet are both communicated with the cylindrical groove; and a regulator is arranged in the cylindrical groove. Through the left inlet and the right inlet,air flows through the cylindrical groove and is discharged from the outlet through the silicon diaphragm, the pressure is detected by utilizing the effect of the airon the silicon diaphragm, and opening and closing of the left inlet and the right inlet can be controlled by utilizing the regulator, so that the free control of the inlets of the pressure sensor is realized, the detection efficiency is improved, and the effects of free control and efficient detection are achieved.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a pressure sensor with a double intake pipe structure. Background technique [0002] A pressure transducer (Pressure Transducer) is a device or device that can sense pressure signals and convert the pressure signals into usable output electrical signals according to certain rules. A pressure sensor usually consists of a pressure sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. Pressure sensor is the most commonly used sensor in industrial practice. It is widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemical, oil wells, electric power, ships, machine too...
