BL-YW-SF11D PP Liquid Level Switch

BL-YW-SF11D

PP magnetic float level sensor refers to a sensor that uses a magnetic float made of polypropylene material for liquid level measurement. PP is a common engineering plastic with good chemical resistance, high temperature resistance, and mechanical strength. This kind of sensor usually includes a floating ball embedded with magnetic material, usually permanent magnet material or other magnetic materials, which makes the floating ball magnetic and can be affected by external magnetic fields. And there are magnetic sensing devices around the sensor, which can be Hall effect sensors, magnetoresistive sensors or other magnetic sensors. These sensors can detect changes in the magnetic field. When the liquid level changes, the magnetic float will rise or fall accordingly, thus affecting the magnetic field in the sensing device. The sensor determines the level of the liquid by detecting changes in the magnetic field.

The principle of floating ball magnetic liquid level switch is equipped with a powerful constant magnetic field in the floating ball of the pole. Due to the rise or decrease of the liquid level, the magnetic field generated inside the floating ball triggers the dry reservoir in the pole to generate action. Widely used in the field of liquid level measurement, liquid level alarm and liquid level safety control.
