Here mainly introduces the detection method of electric current, find some factors that are easy to be neglected in the design. First consider two different methods: the detection method based on the magnetic field and the detection method based on the shunt. 1. Magnetic field-based detection methods (represented by current transformers and Hall sensors) have many advantages, such as good isolation and low power loss, which makes it more widely used in power drive technology and high current fields, but It also has shortcomings, such as large size, unsatisfactory compensation characteristics, linearity, and temperature characteristics. 2. Shunt method High-precision low-resistance resistors currently have the characteristics of high power and small size. This method has low cost and high accuracy. More used in automotive electronics. If you want to realize the anti-pinch function, you usually use two methods for detection at the same time. The following takes the window control as an

One of the components of an engine is the valve. Engine valves are mechanical components that support internal combustion. One approach is the consumption of compressed air. Based on experiences from valve manufacturer (Desu Automatic Manufacturer. Co.,Ltd), around 500 butterfly, 1,000 seat and 1,500 double seat valves are installed in your average large dairy (700 million kg raw materials p.a.). If compressed air consumption could be reduced by just a few percent, this could result in considerable savings. Another way to increase efficiency is to minimize cleaning fluid losses. An NW 65 valve with 2.5 bar line pressure can easily lose almost 2 liters of fluid per second. This loss occurs due to the necessary leakage space in double seat valves, which is cleaned when the valve disc is raised. To prevent the loss of too much cleaning fluid, the response times of the valves must be as short as possible – solutions can be found in their design.   Related products: API 6A Gate Valves , H
