Basic principle of SOR level switches

Thread Content

The rising liquid level lifts the float or spring-driven plunger, causing the magnetic tube to rise into the magnetic field area; this in turn attracts and activates the circuit or pneumatic switch (sending a signal indicating that the liquid level has been reached). When the liquid level drops, the process is reversed: the circuit or pneumatic switch is released (sending a signal that the liquid level has dropped). Magnetic sliders (through sealing sleeves) isolate the permanent magnets and switch components from the process liquid level, preventing magnet corrosion and the accumulation of magnetic debris. Magnetic motion transmission eliminates problems such as fatigue, damage, and premature failure caused by mechanical bending motion transmission. Magnetic motion transmission avoids surface coating issues caused by probe-type sensors. Without the factory’s permission, do not alter the components and structure of the switch.
