Dry reed level switch
Dry reed level switch(CK-1 type,EK-1 type) is used together with UHZ-517 series turn post level meters and installed on the indication panel. It's used to control or alarm the liquid level.
The level switch installed on the indication panel of magnetic turn post level meter and level meter are at the same magnetic coupling system. Floater in the main pipe of level meter moves up and down with the changed level.When floater flows near the level switch from bottom to top, alnico in the floater acts on dry reed pipe in the guide rod,issues on-off switch signal. Normally open reed switch is in the state of connection.when in a magnetic field and in the state of disconnect when outside the magnetic field.While normally closed reed switch contraries to the normally open reed switch in the same state.
