Principle and scope of application of magnetic float level gauge

Main principle

　　 The structure of the magnetic float level gauge is mainly designed and produced based on the principles of buoyancy and static magnetic field. The position of the floating ball with magnet (referred to as the floating ball) in the measured medium of the anti-frost level gauge is affected by buoyancy: the change of the liquid level causes the change of the position of the magnetic float. The magnets and sensors (reed switches) in the floating ball change the number of components (such as fixed-value resistors) connected in series to the circuit, which in turn changes the electrical quantity of the meter circuit system. That is, the change of the position of the magnetic float causes the change of the electrical quantity. Reflect the liquid level in the container by detecting the change of electrical quantity.

　　 The magnetic float level gauge can directly output the resistance value signal, or it can be used with the transmission module, the valve actuator output current value (4-20mA) signal; at the same time, it can output voltage signal or switch signal with other converters. So as to realize the remote transmission, analysis and control of electrical signals.

Application scope and characteristics

　　 Magnetic float level gauge has the advantages of simple structure, convenient use, stable performance, long service life, easy installation and maintenance of high temperature solenoid valve. Magnetic float level gauges can almost be applied to liquid level measurement and control in various industrial automation process control, and can be widely used in petroleum processing, food processing, chemical industry, water treatment, pharmaceuticals, electric power, papermaking, metallurgy, ships and boilers Liquid level measurement, control and monitoring in other fields.
