As a  Linear Sensor Factory , share with you. Linear sensors is a quantity related to the movement of the position of an object during movement. The range of displacement measurement methods is quite extensive. Small displacement is usually detected by strain type, inductive type, differential transformer type, eddy current type,  Linear Hall Sensor , and large displacement is usually measured by sensing technology such as induction synchronizer, grating, capacity grid, magnetic grid and so on. Among them, the grating sensor has the advantages of easy digitalization, high accuracy (currently the highest resolution can reach nanometer level), strong anti-interference ability, no artificial reading error, convenient installation, reliable use, etc., in the machine tool processing, testing instrument and other industries. Is increasingly widely used. Linear Hall Sensor Construction safety is a safety issue encountered in engineering construction in various industries. Constructio

Magnetic Sensor  is a device that converts the magnetic properties of sensitive elements caused by external factors such as magnetic fields, current, stress and strain, temperature, and light into electrical signals. In this way, it detects corresponding physical quantities. Magnetic sensors are widely used in modern industrial and electronic products to measure physical parameters such as current, position, and direction by inducing magnetic field strength. In the prior art, there are many different types of sensors for measuring magnetic fields and other parameters. Magnetic sensors are devices that detect changes in the magnetic properties of sensitive components caused by external factors such as magnetic fields, current, stress and strain, temperature, and light, and convert them into electrical signals. There are three types of magnetic sensors: compass, magnetic field sensor, and position sensor. Compass: The earth generates magnetic fields. If you can measure the magnetic

Fifth, Wiegand output signals can be transmitted remotely using telephone lines and coaxial lines. Use

In recent years, with the development of China's economy, China's bridge construction has ushered in an unprecedented development speed, providing a solid transportation infrastructure for economic construction. With the improvement of bridge construction and transportation systems, bridges have also been over-managed from large-scale construction to bridge monitoring and evaluation. As time goes by, more and more bridges will reach or approach the service life, and the heavy pressure of vehicles will be accepted over the years, causing structural damage and aging of the bridges, especially for large bridges. The loss of recovery. Therefore, health and safety monitoring of bridges is essential. In the past, the monitoring of the health and safety of bridges was mainly based on manual inspections. Although it was supplemented by corresponding testing equipment, it was difficult to monitor the bridges in real time and continuously, and the monitoring methods were not intellige

The features of  China Hall Sensor  include: miniaturization, digitization, intelligence, multi-functionality, systematization, and networking. It not only promotes the transformation and upgrading of traditional industries, but also may establish new industries, which will become new in the 21st century. The point of economic growth. Miniaturization is based on microelectromechanical systems (MEMS) technology and has been successfully applied to silicon devices as silicon pressure sensors. Next, let's share with you how to judge the quality of the linear hall sensor. Linear Hall Sensor 1.Linear range The  Linear Hall Sensor 's linear range is the range in which the output is proportional to the input. In theory, within this range, the sensitivity remains constant. The wider the linear range of the displacement sensor, the larger the range and the certain measurement accuracy. When selecting the displacement sensor, when the type of the displacement sensor is determi

The resolution of the  Linear Hall Sensor  is essentially how much displacement can produce an identifiable electrical signal. For example, a displacement sensor measures the displacement of an object. If the displacement is below one micron, the probe does not react. If the displacement exceeds one micron, it will change. The output of the probe, then say that this micron is the resolution of the probe. Linear Hall Sensor Accuracy has a lot of understanding, it may refer to absolute error or linearity. To put it bluntly, is your ruler accurate or not. One micrometer you measured, how much different from a micrometer of the metrology standard. Others will say repeatability as precision. In fact, he said that under the same measurement conditions, only the probe is removed and then reset to the same measurement point, and the measurement results are drifted. Or do not remove the probe, just look at it after a while, whether the measurement results drift. The relationship betw
