The Internal Structure Of The Switching Hall

Switching hall includes Unipolar Hall, bipolar hall and full-pole hall. A switching hall consists of a regulating circuit, a hall generator, a signal amplifier and a digital output stage.
1. Regulating circuit: the regulating circuit has two functions, one is the reverse protection function, that is, when the input terminal of hall is suddenly applied a reverse voltage or the hall wire is connected with the reverse, hall can still maintain the normal working state. The other function is to stabilize the voltage circuit and keep the voltage in a safe range.
2. Hall generator: from several uV to several mV according to different requirements.
3. Signal amplifier: signal amplifier has the function of amplifying hall's output analog signal and magnetic threshold detection, that is, the signal is converted to digital signal according to the preset BOP or BRP.
4. Digital output level: connect the collector open-circuit output to the external interface, which can interface with TTL and CMOS circuit.
Because hall of different materials has different advantages and disadvantages and applications, if you want to know more about Bipolar Hall IC or Linear Hall Sensor.Pls feel free to contact us,we will give the professional answers to your questions.

Omnipolar Hall IC

图片
  Omnipolar Hall IC The omnipolar Hall-effect sensor  includes the following on a single silicon chip: reverse voltage protector, voltage regulator, temperature compensation circuit, Hall-voltage generator, signal amplifier, Schmitt trigger and open-drain output driver, etc. Produced with CMOS technology, an omnipolar Hall IC is asked for lower supply voltage and less power supply. It is available in two package types: SOT-23-3L (Type M) and TO-92UA (Type UA). More detail of China Hall Sensor , please via: https://www.ahest.net/

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
