The Process Technology Of Hall Effect Sensor

图片
In order to accurately distinguish the cause of  Hall Effect Sensor  abrupt signal generation, a wavelet band analysis method based on mathematical model is proposed. For the measurement and control system in industrial process, the relationship between the frequency composition of the output mutation signal and the cause of the mutation is analyzed. Using wavelet band analysis technology, the high and low frequency signals are separated, and energy statistics are performed. According to the change of the energy ratio of high and low frequency signals, the cause of the mutation signal is judged. The computer simulation of the classic control system and the experimental results of the constant pressure water supply system show that the method can effectively diagnose whether the  Magnetic Sensor  is faulty. In the measurement and control system, the output signal of the sensor is affected by many factors, and often abrupt changes. These mutation point values contai...

What is the difference and connection between the resolution and accuracy of the Linear Hall Sensor?

图片
  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 relationsh...
