Product Overview

UQK-80 multi-point float  level switch is suitable for level control or alarm of liquids in open or sealed vessels in the field of petroleum, chemical, textile printing and dyeing, environment protection and civil architecture etc. Simple in structure, easy to install, low in cost, the switch can be used for level control of various liquids. Multi-floats are used to control different level points respectively, which make the operation more reliable.

Structure Principle

The float with magnet inside will move as liquid level rises, the dry reed pipe in guide tube will be divided or combined.

Reed switch shares the same level position with the pre-checked or alarm level; the probe rod is used to guide the float orientation. Float moves up and down as the guide rod, the reed switch is closed when near the magnetic field, open when away from the magnetic field.
