  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 between acc

  Linear Hall Sensor   causes errors 　　1.Zero error 　　The zero error is caused by the unequal potential. The main reason for generating the unequal potential is that the two Hall electrodes are not mounted on the same equipotential surface; the unevenness of the material causes uneven distribution of resistance, poor contact of the control electrodes, and uneven current distribution. 　　2. Parasitic DC potential error Linear Hall Sensor 　　The main reason for the parasitic DC potential is that the control electrode is in poor contact with the Hall element, forming a non-ohmic contact. The two Hall electrodes are asymmetrical in size, so that the heat capacity of the two electrodes is different, the heat dissipation state is different, and the temperature difference potential between the two electrodes occurs. , causing the Hall element to produce temperature drift. 　　3. Inductive zero potential error 　　When the Hall element operates in an AC or pulsating magnetic field, even if the contr

  　Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into two types: physical size measurement and mechanical displacement. According to the form of the measured variable transformation, the displacement sensor can be divided into analog and digital. The analog type can be divided into two types: physical type and structural type. Common displacement sensors are mostly analog structures, including potentiometer displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, and   Linear Hall Sensors . An important advantage of digital displacement sensors is the ease with which signals can be sent directly to a computer system. Such sensors are rapidly evolving and are becoming more w

  　　Modern   Linear Hall Sensors   vary widely in principle and structure. How to properly select displacement sensors according to specific measurement purposes, measurement objects and measurement environment is the first problem to be solved when performing a certain amount of measurement. When the displacement sensor is determined, the matching measurement method and measuring device can be determined. The success or failure of the measurement results depends to a large extent on whether the selection of the displacement sensor is reasonable. So how do you judge the displacement sensor as a   Linear Sensor Factory ? Determine the type of displacement sensor based on the measurement object and the measurement environment. Linear Hall Sensors 　　To carry out a specific measurement work, we must first consider the principle of the displacement sensor, which needs to be analyzed after analyzing various factors. Because even if it is measuring the same physical quantity, there are many k

Also in order to ensure linearity, a magnet with a high magnetic field strength is required, which produces a large change in magnetic field strength for the required movement. There are several possible paths of motion for detecting the magnetic field, and the following are two more common sensing configurations that use a single magnet: head-on detection and sideways detection. Hall Effect Sensor Front detection As the name implies, "frontal detection" requires the magnetic field to be perpendicular to the Hall-effect sensing device, and in order to perform detection, the magnetic field must be directly close to the sensor toward the active surface. A "frontal" approach. This positive method produces an output signal V H. In a linear device, this signal represents the magnetic field strength, the magnetic flux density, which is a function of the distance from the Hall effect sensor. The closer the magnetic

  As a   Latch Type Hall Sensor Factory , share with you. The second sensing configuration is "side detection". This requires the magnet to move on the surface of the Hall effect element in a lateral movement. Lateral or sliding detection is useful for detecting the presence of a magnetic field, such as when the magnetic field moves across the surface of the Hall element within a fixed air gap distance, for example, to calculate the speed of a rotating magnet or motor. Omnipolar Micropower Hall Effect Sensor According to the position when the magnetic field passes through the center line of the sensor zero fields, a linear output voltage that represents both a positive output and a negative output can be generated. This allows directional motion detection, which can be vertical or horizontal. Hall effect sensors have many different applications, especially as proximity sensors. If the environmental conditions include water, vibration, dust or oil, for example in automotive ap
