Hall Sensor

The Hall effect is the working principle of the Hall sensor. It is a kind of electromagnetic effect, in which an orthogonal current and magnetic field are applied to the Semiconductor. The carriers in the Semiconductor are subjected to the Lorentz force and deflected. In different directions Gathering, thereby generating an electric field. There is a built-in voltage, this voltage is the Hall voltage, the greater the magnetic field strength, the greater the Hall voltage.

Hall sensor

The working principle of the linear Hall sensor, the output of the linear Hall sensor is an electrical signal proportional to the measured magnetic field strength. For example, the linear Hall sensor 3503 has three pins which are positive VS, V out and GND. Among them The positive VS is connected to a power supply of 4.5 to 6V. Power is supplied to the 3503, and the GND is grounded. The shell of the 3503 can induce the magnetic field, and implements the magnetic field strength in the form of voltage output at the pin of V out. The next output diagram shows that the 3503 is good When the magnetic field strength is 0 Gauss, V out is equal to 2.5V. When the magnetic field strength changes by 1 Gauss, the output changes about 1.3 millivolts.
When the 3503 sensor measures the magnetic field, it needs to pass the magnetic field lines through its effective sensing element to be detected. The magnetic field lines pass through the Hall sensor. The stronger the magnetic field, the more magnetic field lines pass through the Hall sensor, and the weaker the magnetic field passes through. The fewer lines of magnetic force, the Hall sensor outputs a corresponding signal to indicate the strength of the magnetic field according to the number of magnetic lines that pass through.

Drive the preferential presetting of the spring frame of the vehicle

The secondary spring system of the original electric locomotive consists of 4 sets of the same ordinary cylindrical compression springs. Its parameters are: spring material diameter d=48mm, maximum working circle diameter D=230mm, effective working circle number n=6.6, free height H0= 528mm, working height H=431mm. The characteristic curve of the spring is approximately straight, with stable stiffness and simple structure. However, the spring stiffness is mainly along the axial direction, and its transverse shear and bending stiffness is very poor, and its anti-resonance ability is poor. After the train speeds up, its snake-like movement and shaking phenomenon intensify. Therefore, it is necessary to improve the spring system of electric locomotives. Improvement of the spring system. The improved spring parameters and characteristics take into account the special position of the secondary spring (between the bogie and the car body) and specific functions (s...

How are the CNC Machining Manufacturers in Shenzhen? China Hardware Has Carried out Comprehensive Comparison with Multiple Dimensions in Various Regions

Keywords: Cnc Machining manufacturers,CNC Machining,How about Shenzhen CNC Machining manufacturers I'm not afraid of the quality of the product, I'm afraid to shop around. There is no contrast and no injury, this has been known to everyone since ancient times. For example, Shenzhen CNC Machining manufacturers, if you can find more Shenzhen CNC Machining manufacturers to compare their products, and compare the strengths of Shenzhen CNC Machining manufacturers, you will find that what you see with the naked eye is not all right, there may be some Unidentified objects participate in it, how do you compare them, and what aspects should you start with? Let's see how you do it. Everyone says to shop around. So, what is the comparison? Here is an explanation. Duowei Shenzhen is looking for suitable Shenzhen manufacturers for CNC Machining: 1. There are various qualification certificates: such as: business license, ISO, equipment distribution, enviro...
