The Difference Between Bpolar Hall And Omnipolar Hall

Bipolar Halls and Omnipolar Halls are currently commonly used Hall elements and are widely used in applications such as switching, speed measurement, and metrology applications. However, in practice, many people mistake the bipolar as an omnipolar hall as a bipolar Hall. Extremely, causing troubles when building hall circuits or designing circuits. Today we will elaborate on how to correctly distinguish between bipolar Hall elements and omnipolar hall elements.
1. Bipolar Hall element
 Bipolar Halls generally have to specify a magnetic pole. At the same time, two magnetic poles are required to control the high and low levels respectively, and the magnetic field NS pole is alternately used to output signals. If the S pole is close, it outputs a low level, and when the N pole is close, it outputs a high level. Typical applications for bipolar Halls are speed measurement or counting. If the magnetic field is removed, it is a random output, either open or closed.
Bipolar Hall element features: good stability, high sensitivity, wide voltage, good consistency and long life.
 Typical applications for bipolar Halls: motor speed, speed sensors, pulse counters, encoders, fans, etc.
2. Omnipolar Hall element
 The Omnipolar Hall is also called the non-polar Hall. The induction method is: the omnipolar hall does not distinguish the south (S) north pole (N) to detect the magnetic field, the magnet outputs a low level when approaching, and outputs a high level when it is far away. The polarity of the hall is similar to that of the unipolar Hall. The difference is that the unipolar Hall switch specifies the pole, while the omnipolar Hall switch does not specify the pole. Any pole is close to the output low level signal. Leave the output high level signal.
Omnipolar Hall element features: low voltage, low power consumption, high sensitivity
 Typical application applications for omnipolar hall: switches, mobile phones, smart water meters, portable electronic devices, bluetooth headsets, etc.

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
