overview：

The UQK-60 series float level switch is suitable for level control in open or pressurized containers during industrial production processes. Float switches are divided into two categories: explosion-proof and non explosion-proof. It is safe to use, reliable in performance, and easy to maintain. Overcoming the drawback that other types of controllers can only be maintained during major repairs. But this instrument is not suitable for media with high viscosity, easy crystallization, and corrosive effects on stainless steel.

UQK-60A/B series float level switch:

Structural principle:

The UQK-60A/B series float level switch uses a float as the sensing element and is rigidly connected to a magnetic force. Install a permanent magnet on the switch mechanism that rotates on the fulcrum. When the float rises with the liquid level, it lifts the magnetic block on the inner connecting rod and enters the magnetic field of the magnet. Then, the magnet quickly closes the non-magnetic sealing sleeve, causing the switch to operate. The sealing sleeve provides a static pressure boundary between the switch mechanism and the process. When the liquid level drops, the reset spring causes the magnet to retract, thereby releasing the action of the switch mechanism, controlling the liquid level, and triggering an alarm. Implemented automatic liquid level control process.

principle：

The UQK-60E top mounted float (ball) liquid level switch is based on the principle of buoyancy, which uses the float as the sensing element. Two floats are suspended on a steel wire rope at the same time, that is, the spring is loaded by the float heavier than the liquid. When the float sinks in the liquid, the buoyancy changes, causing the spring to move upward.
The upper end of the spring is connected to the magnetic tube. Install a permanent magnet on the switch mechanism that rotates on the fulcrum. When the float rises with the liquid level, it lifts the inner connecting rod into the magnetic field of the magnet, and then the magnet quickly closes the non-magnetic sealing sleeve, causing the switch to operate. The sealing sleeve provides a static pressure boundary between the switch mechanism and the process. When the liquid level drops, the reset spring causes the magnet to retract, thereby releasing the action of the switch mechanism, controlling the liquid level, and triggering an alarm. Implemented automatic liquid level control process.
