Magnetic liquid level switch is a high and low liquid level alarm device used in conjunction with UTZ series magnetic float level gauge. The magnetic liquid level switch outputs switching signals and has memory retention, which is stable and reliable until it is widely used. Mainly used for high and low liquid level alarm of various liquid level storage tanks, separation tanks, heating tanks, water tanks and other containers in explosive environments of petroleum and chemical systems. The magnetic liquid level switch can be used in conjunction with our factory's B-1 type (sound and light) alarm.

 

Working principle:

The switch is made of dry reed memory switch group with stable and reliable performance. Its working principle is that when the float of the magnetic float level gauge floats up and down with the liquid level, the magnetic force in the float acts on the switch and memorizes it, so that the switch is in an open or closed state.
