Pressure sensor is the most commonly used sensor, which is widely used in various industrial self-control environments, involving water conservancy and hydropower, railway transportation, intelligent building, production automation, aerospace, military, petrochemical, oil well, electric power, ship, machine tool, pipeline, etc. In many industries, the following is a brief introduction to the application of some common pressure sensors.
An industrial automation system is usually divided into three parts: detection, control, and execution. Industrial equipment, as the control object of the automation system, must be compatible with the other two parts, providing a pressure sensor interface to make it a complete organic whole. Whether it is stand-alone automation or large-scale automation, the control object should be protected to maximize its use.
Application of pressure sensor in weighing systemPressure sensing technology is increasingly being used in commercial weighing systems for industrial control technology.
In many pressure control processes, it is often necessary to collect pressure signals and convert them into electrical signals that can be automatically controlled.
Pressure control devices made with pressure sensors are commonly referred to as electronic weighing systems, and electronic weighing systems are becoming increasingly important as online control tools for material flow in various industrial processes. The electronic weighing system can not only optimize the production in the product manufacturing process, improve the product quality, but also collect and transfer the data about the material flow in the production process to the data processing center for online inventory control and financial settlement.
In the process automation of weighing, the pressure sensor is required not only to sense the gravity signal, but also the performance must be reliable, the dynamic response is better, and the anti-interference performance is better; the signal provided by the pressure sensor can be directly displayed, recorded, and stored by the detection system. Or for feedback adjustment control.
The integrated technology integrates the pressure sensor with the measuring circuit, which greatly reduces the volume of the whole device. In addition, the development of the shielding technology will also ensure the anti-interference ability of the weighing pressure sensor, and the degree of automation control of the weighing process. Further improved.
Application of pressure sensor in petrochemical industryThe pressure sensor is one of the most used measuring devices in the automatic control of the petrochemical industry. In large chemical projects, almost all pressure sensor applications are included: differential pressure, absolute pressure, gauge pressure, high pressure, differential pressure, high temperature, low temperature, and remote flange pressure sensors of various materials and special processing. .
Almost all of the petrochemical industry's demand for pressure sensors is focused on reliability, stability and high precision. Among them, reliability and many additional requirements, such as range ratio, bus type, etc., depend on the structural design of the transmitter, the level of machining technology and structural materials. The stability and high precision of the pressure transmitter are mainly guaranteed by the stability and measurement accuracy of the pressure sensor.
Corresponding to the measurement accuracy of the pressure transmitter is the measurement accuracy and response speed of the pressure sensor. Corresponding to the stability of the pressure transmitter is the temperature characteristics and static pressure characteristics of the pressure sensor and long-term stability. The demand for pressure sensors in the petrochemical industry is reflected in measurement accuracy, rapid response, temperature characteristics, static pressure characteristics, and long-term stability.
The micro pressure sensor is a new type of pressure sensor manufactured by semiconductor materials and MEMS technology. It has the advantages of high precision, high sensitivity, good dynamic characteristics, small volume, corrosion resistance and low cost. The material of pure single crystal silicon has low fatigue, and the micro pressure sensor made of this material has good long-term stability. At the same time, the micro pressure sensor is easy to integrate with the micro temperature sensor, which increases the temperature compensation accuracy and greatly improves the temperature characteristics and measurement accuracy of the sensor.
If two micro-pressure sensors are integrated, static pressure compensation can be implemented to improve the static pressure characteristics of the pressure sensor. Today, micro-pressure sensors have many of the advantages that traditional pressure sensors do not have, and are well suited to the needs of pressure sensors in the petrochemical industry.
Application of pressure sensor in water treatmentChina's environmentally friendly water treatment industry has developed rapidly in recent years and has broad prospects for the future.
The use of pressure sensors in water supply and wastewater treatment processes provides important control and monitoring tools for system protection and quality assurance.
The pressure sensor converts the pressure (generally the pressure of the liquid or gas) into an electrical signal output, which in turn can be used to measure the level of the static fluid and can therefore be used to measure the liquid level. The sensitive components of the pressure sensor are mainly composed of a silicon cup sensitive component, a silicone oil, an isolating diaphragm and an air guiding tube. The measured medium pressure P is transmitted to one side of the silicon cup component through the isolating diaphragm and the silicone oil (see figure), and the atmospheric reference pressure po The gas cup is applied to the other side of the silicon cup element, which is a cup-shaped single crystal silicon wafer which is thinly processed at the bottom. The bottom film of the cup produces elastic deformation with minimal displacement under the pressure P and Po. The single crystal silicon is an ideal elastic body, and its deformation has a strict proportional relationship with the pressure, and the recovery performance is excellent.
The four bridge resistors formed by the semiconductor diffusion process on the silicon diaphragm are arranged in a square shape. When the silicon diaphragm is deformed by pressure, the two resistors on the diagonal are subjected to compressive stress, and the other two resistors are subjected to tensile stress. Due to the piezoresistive effect of the diffused silicon, the resistance values ​​of the two opposing resistors are increased, and the resistance values ​​of the two resistors are reduced. If a voltage is applied to the two ends of the AA, there is a voltage signal output proportional to the P-Po differential voltage between the CDs.
What is an industrial router? Which industries are they mainly used in?
With the continuous development of the network and the continuous progress of various industries, some new concepts and development directions have actually emerged during the period. For example, from the current point of view, many enterprises in the development process in order to have good efficiency and speed, as well as the use of more functions, gradually began to use industrial routers. Of course, for this type of router, we also have a lot of problems, so today we will discuss to see, what is an industrial router? Which industries are they mainly used in?
What is an industrial router?
From the basic concept, an industrial router is a wireless data transmission function that provides users with wireless data transmission through a public wireless network. For example, we use mobile phone data to transfer things to another mobile phone or computer, in fact, the principle is very simple. Of course, the specific usage operation is different. In the process of use, the industrial router has the advantage of allowing multiple users to use the same integrated network system to access the network, which is also very convenient in the work. In fact, at present, industrial routers are gradually widely used in different industries, and the practicability is also very strong.
Industrial routers are mainly used in what industries?
The first is some of the contents summarized for the concept and basic principles of industrial routers, and for the use of industrial routers, it is also some of the issues that we are concerned about. From the current point of view, the first is widely used in intelligent transportation, such as in the application of high-definition electronic bayonet, road wireless video surveillance, vehicle monitoring or security monitoring, etc., which is also very important; Secondly, it is also widely used in the financial industry, such as the use of wireless atm self-service terminals, wireless pos machines or other applications; In addition, it is the application of the power industry, such as transformer remote monitoring management, circuit line video surveillance and substation video surveillance and so on. In short, the use of industrial routers is also more extensive.
How to choose an industrial router?
Although the industrial router is widely used now, the choice we made at the beginning is still more tangled, from the feedback of the market, Movingcomm router is actually very good. According to the needs of the industry environment, based on SD-WAN+ Internet of Things, intelligent networking can then be formed into a large local area network through the cloud platform router in many places. Therefore, the focus of security monitoring can also be concentrated to complete the work of remote video surveillance, but also to meet the needs of remote working, for some of the industries we mentioned earlier, the practicality of this program is also very good. Moreover, the technology of remote networking and intelligent networking is also very mature, and the security and stability are also good. In short, the advantages of Movingcomm router are still many.
