Water Flow Sensor Magnets
Water flow sensor is a type of water flow induction instrument which output pulse, current or voltage signal through induction to the water flow. The output of the signal has a certain linearly proportional to the water flow. Thus can be served to the management of water control and flow calculation depend on the relevant conversation formula and comparison curve. Actually, as a core component of water flow sensor, water flow sensor magnets have long been a typical application of injection molded ferrite magnet.
Working Principle of Water Flow Sensor
Water flow sensor is mainly composed of copper valve body, water flow rotor assembly, steady flow system and hall component. Water flow sensor is usually installed on the inlet of the heater to measure influent flow, and magnetic rotor assembly rotates when water flow through it. Hall component output and feedback corresponding pulse signal to controller, then controller adjust current of proportional valve and hence gas usage according to the flow rate.
Water flow rotor assembly mainly consists of turbine switch housing, magnetic rotor, and brake ring. Water flow sensor magnets are essentially a hall effect sensor magnet. Hall component will conduct when different magnetic poles toward it, then cut off once away.
Injection Magnet Plastic Magnet What is Injection Moulding
Magnet material can be directly molded into, onto, or against other assembly components eliminating subsequent assembly steps. This is called insert injection molding.
Injection molded magnets are available by using ferrite, neodymium-iron-boron, or blends of magnetic materials to achieve an extensive range of properties. Binder materials include Nylon 6 and 12, PPS, and Polyamide. The binders and magnetic alloys are capable of a wide range of working temperatures from below -40°C to above 180°C. The Injection molding process allows the ability to produce very intricately shaped magnets with extremely tight tolerances and a wide variety of physical and magnetic characteristics. The finished parts can be either very simple or complex in geometry. Radial Multipole Flow Sensor Rotor Magnets
The properties of injection molded magnets vary greatly, depending on the type of magnetic material and binder utilized. HSMAG has both Neodymium and Hard Ferrite injection molding capability, and it is also possible to utilize a blend of different magnetic material to produce the desired properties. Several types of binder can be employed depending on the application, and we offer a variety of nylon and PPS grades to suit the specific needs of our customers.
