? I'll answer; book: design, manufacture and application of pressure sensors ? Precision Steel Tube Pressure Sensor is a widely used sensor in various industrial fields, commonly used to measure the pressure of gases or liquids inside pipelines, vessels and other equipment. This article will introduce how to manufacture a common pressure sensor, including its main components, material selection, production technology and inspection process.
A, the main components are usually, a pressure sensor consists of the following main parts: sensitive element: it is the core of the sensor, responsible for converting the pressure signal into an electrical signal. Currently on the market there are four main types of sensitive elements: elastomer, capacitive, piezoresistive and pressure plate type. Different types of sensitive elements are suitable for different pressure ranges and accuracy requirements. Support structure: The sensitive element needs to be firmly supported in the sensor housing to ensure its sensitivity and stability. The support structure is usually made of materials such as metal or ceramic. Housing: housing is the sensor shell, play a role in protecting the sensitive components and support structure. Housing is generally made of stainless steel and other corrosion-resistant, high-temperature-resistant materials. Connector: The connector is responsible for connecting the sensor to the measurement system and outputting the signal to the instrument via a wire. The connector needs to be electrically insulated and high temperature resistant.

.Second, the material selection of different application scenarios and precision requirements need to choose different materials. The following is a list of the scope of application of several common materials: Elastomer sensitive components: mainly for low-pressure, low-precision occasions, such as meteorological observation. The materials are usually rubber, silicone, neoprene and so on. Capacitive sensitive elements: suitable for low to medium pressure, higher precision occasions, such as aviation, military industry and other fields. The material is usually ceramic or metal film. Piezoresistive sensitive components: suitable for high pressure, low precision occasions, such as compressors, hydraulic systems. The material is usually steel, silicon, etc. Pressure plate sensitive element: suitable for high pressure, high precision occasions, such as oil fields, chemical industry and other fields. The material is usually titanium alloy or stainless steel.
Three, the production process to manufacture a precise Design, manufacture and application of Precision Steel Tube Pressure Sensor? Need to go through a rigorous production process. The following is a basic production process: Preparation of sensitive elements: according to the pressure range and precision requirements to select the appropriate material, prepared into different shapes of sensitive elements. This step requires attention to the cleanliness and ventilation of the environment to avoid contamination by impurities. Assembling the support structure: Paste or weld the sensitive elements onto the support structure, and add compensation diaphragms, sealing gaskets and other auxiliary materials. At this point, it is necessary to use microscopes and other fine instruments to check the quality of the support structure. Encapsulation of the housing: the support structure and sensitive components are installed into the housing, and the connectors and cables are installed. Calibration and testing: Use equipment such as standard gas sources or liquid pressure gauges to calibrate the sensors and check whether their parameters such as sensitivity, accuracy and stability are in accordance with the regulations.
Four, the inspection process of a high-quality pressure sensor must undergo a number of quality inspection procedures before being used. The following are some common inspection process: dust test: the sensor into a clean airtight environment, observe whether there will be dust, bacteria and other contamination. Low and high temperature test: The sensor is placed under very low or very high temperatures for a certain period of time to detect changes in its performance. Shock test: The sensor is subjected to mechanical shock, vibration or oscillation tests to detect its stability. Drainage resistance test: Use resistance testing equipment to connect the sensor to the ground to check whether the drain resistance is in accordance with the regulations. Accuracy calibration: using standard pressure gauges or other measuring equipment, the sensor for multiple calibration, and check whether its output signal is stable and accurate. Summary The above are some common manufacturing?
? I came to answer ; Precision Steel Tube Pressure Sensor the basic points. Of course, a more complete production process needs to include quality tracking, records management, and much more. Only through constant and strict quality control and technological innovation can we produce more excellent sensor products to provide better support for industrial automation.
