What Is a Hall Sensor?

The Hall sensor is a magnetic field sensor that is fabricated according to the Hall effect. Hall was invented in 1879 when studying metal conduction mechanisms, and this effect was found in both conductive fluids and semiconductors. It is widely used in detection technology, information processing and industrial automation technology. Hall IC has many characteristics. It is small in size, light in weight, easy to install, low in power consumption, high in frequency and long in life. It is resistant to vibration, water vapor, salt spray and dust.

Hall IC

Hall Effect Technology has a wide range of applications in the automotive industry, taxis, and frequency converters, including automotive body power control, anti-lock braking systems and traction control. The taxi is mainly used for the meter on the taxi. According to the sensor on the loading wheel, the mileage can be calculated. The inverter is mainly used to protect the high-power transistor in the inverter. When a short circuit occurs, the power supply will be cut off in time to protect the transistor.

Method Of Detecting Switch Type Hall Sensor

图片
In the use of hall sensor for maintenance machinery, we will encounter holzer not working, from holzer's shape can not distinguish whether the holzer element is damaged, and how to detect whether the switch type of hall sensor is damaged. Taking Holzer YS282 as an example, the test method of switch type Holzer element is as follows: First, find a resistance R of 1K Omega, which is connected to the figure 1 and 3 feet, and connect the positive pole of the DC power of the 12V to the foot of the  switch type hall sensor YS282, and the anode is connected to the foot. The multimeter is placed in a DC 50V file, the red pen is connected to the foot, and the black pen is connected to the foot, and the pointer changes of the multimeter are observed. When the magnet N is very close to the test point of the hall sensor YS282, the pointer of the multimeter is deflected from the high level to the low level; when the N pole of the magnet is far away from the test point of the Holzer element Y

How To Use Water Flow Sensor？

图片
The  Water Flow Sensor  consists of a plastic valve body, a water rotor and a Hall Effect Sensor. When the water flows through the rotor, rotor rolls and the speed of it changes with a different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This type of sensor can be found on different diameters, water pressure (MPa) and flow rate (L/m) ranges. Make sure to select one that will cover your needs. The sensor that I have it has 20mm diameter, <1.75Mpa water pressure and ~30 L/m flow rate range. A  Water Flow Meter Sensor  is a device that measures the amount of water flowing through a pipe. There are several water flow meter technologies to choose from depending on the water measurement application, maintenance requirements, and budgetary terms.  Each of these types of water flow meters has a unique principle of operation, specific application benefits, and overall cost-of-ownership. The question is: What water flow meter should you choose for your w
