float level switches

Detailed Product Description

UQK-A type magnetic floater liquid level switch

1)function and principle

UQK-A type magnetic floater liquid level switch is composed of magnetic float ball, floater stabilizing tube, reed tube switch, explosion proof wire-connecting box and fixing components. magnetic float ball goes up and down along tube with liquid level, so as to make reed tube contact make and break instantly, output relative control signal. The action of reed tube contacting instantly make and break which matches with relay circuit can complete multifunction control. The contact wont produce electric spark because of reed contact is entirely sealed in glass which filled with inactive air, very safe to control.

2)UQK-A type magnetic floater liquid level switches have some different control types as follow:     

Feed liquor control

4)method of application

When installing, please inspect magnetic floater and experience of floater-stabilizing leader. there should not have bend, impact, crackle, and magnetic should can slide in the leader without resisting, explosion proof connecting box undamaged and make sure the upper cover tight.

Can use multimeter, according to wiring diagram, coordinate with the moving of magnetic floater to check whether the switch can work well.

Adjust the up stop button and the down stop button and tightening it up.

When all of them are normal, break the electric source, install and connect wire.
