Hall's Application In Household Dishwashers

Household dishwashers are one of modern smart appliances. The structure of the dishwasher is mainly composed of: an outer box body, an inner box body, a dish rack, an injection structure, an impeller or a spray arm, a motor, a washing pump, a drainage pump, a program controller, a pressure switch, a solenoid valve, a heater and the like.
Hall IC
According to the washing method, it can be divided into two types: nozzle type dishwasher and impeller type dishwasher. The common principle of the washing principles of the two dishwashers is to use a motor to drive the washing pump or the impeller to rotate, so that the water stream can be used to wash the dishes with strong force to achieve the purpose of washing.
The Hall element plays a role of position commutation in the motor. When the rotor in the motor passes through the Hall element, the magnetic field of the permanent magnet rotor causes the energized Hall element to output the voltage, the circuit is turned on, and the power is supplied to the corresponding stator winding, thereby generating a magnetic field with the same polarity as the magnetic field to repel the rotor.
Because Halls with different materials have different advantages and disadvantages and applications, if you want to know more Hall knowledge and Hall models, including Linear Hall IC and Bipolar Hall IC. Please contact us!

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
