How is Hall Effect Sensor Applied in Measuring Car Speed?

图片
As a  Micropower Hall Effect Sensor Manufacturer , let me share with you the application of  Hall Effect Sensor  in measuring car speed. Micropower Omnipolar Hall Sensor Hall-type speed sensor: Hall Effect Sensor is very special in automotive applications. This is mainly due to the conflict in the position of the space around the transmission. Hall-effect sensors are solid-state sensors. They are mainly used in crankshaft angles and camshaft positions. Switch ignition and fuel injection circuit trigger, it is also used in other computer circuits that need to control the position and speed of rotating parts. Hall effect sensor or switch, consisting of an almost completely closed magnetic circuit containing a permanent magnet and a magnetic pole part. A soft magnet blade rotor passes through the air gap between the magnet and the pole. A window on the blade rotor allows the magnetic field to be unaffected It passes through and reaches the Hall effect sensor, and the part without

Do you know how to Protect the Sensor from Moisture?

As a  Linear Hall IC Supplier , share with you. As a precise detection device, if the sensor is wet, it will be troublesome. The sensor's damp will affect its accuracy and stability, and it will cause serious failure. If the sensor is used in more important places, it will cause losses. It's pretty bad. In 2008, there was an aircraft crash caused by a sensor being wet. The information obtained by the sensor was deviated from the trajectory. The aircraft was affected by the wrong information of the sensor. The flight speed and elevation angle were wrong, causing the aircraft to get out of control. It is obvious that  Hall Sensor China  is moisture-proof, so how to prevent moisture? Linear Hall IC 1. Encapsulate the resistance strain gauge, that is, cover the strain gauge with a waterproof material; 2. To control the environment or create a low humidity environment, it is necessary to prevent moisture from entering the sealed load sensor; Third, it is necessary to ensu

What should I Pay Attention to when Installing the Sensor?

With the development of the times, sensors are basically applied in various industries, and different types of sensors have different effects in different industries. So what should be paid attention to when installing sensors? Let  Latch Type Hall Sensor Factory   find it out. Hall Effect Sensor First, the size of the mounting hole If the size of the mounting hole is not appropriate, the threaded part of the high-temperature melt pressure sensor is easily worn during the installation process. This will not only affect the sealing performance of the device, but also make the sensor unable to fully function, and may even cause potential safety hazards. Only suitable mounting holes can avoid thread wear. Usually, the mounting holes are used to test the mounting holes for proper adjustment. Second, keep the mounting holes clean It is important to keep the mounting holes clean and prevent the molten material from clogging to ensure the normal operation of the equipment. "

Linear Hall effect sensors Linear Hall Sensor  will pass linear area /nonlinear area/ saturation area during the magnetic induction increases. When there is no magnetic field that applies in sensor (B=0), when the output voltage of sensor is only half of Vcc (Vcc/2); when “N” pole faces mark surface of sensor, and be closed to it gradualy (B→-∞),the output voltage begins to decrease, and the voltage doesn’t reduce with the increased magnetic field; When the “S” pole of magnet faces the mark surface of the sensor and is closed to sensor gradualy (B→+∞), the output voltage of sensor begins to increase, and it doesn’t increase with the increased magnetic field after it reaches saturation voltage.The magnetic and electric transfer characteristic curve of linear sensor is shown as the figure: Hall Effect Sensor  Features Rated working voltage 4.5 V ~ 6 V; Operating temperature range: -40℃ ~ 125℃; Rail to Rail voltage output, Rated output current : 6 mA; Variety of package for
