UQZ floating ball type dry reed tube level gauge switch is composed of three parts: magnetic float ball, sensor and switch. When maglev ball with liquid level change, floating up and down the tube and, in the floating ball in the corresponding position of magnetic steel and sensor on the dry reed pipe, the sensor’s total resistance (or voltage) changes, then the switch will change after the resistance of the up and down (or voltage) signal output to a switch signals, and to realize the opening and closing of infusion pump; The upper and lower limit alarm can be set on the display instrument to realize the position control of liquid level.

The floating ball type liquid level switch is specially used for liquid level detection, field indication signal remote transmission and liquid level alarm of various medium and small pressure and pressure liquid storage tanks. It can be used in various hygienic, toxic, corrosive media and explosive gas dangerous places. There are a variety of installation forms, suitable for all forms of containers.

Floating ball type liquid level switch is adapted to control the pump operation to maintain the liquid level; Automatic loading and unloading of control tank; Control liquid level or supply signal, such as fuel tank, automatic cleaning system, hydraulic tank, low pressure boiler, sewage treatment system.

UQZ floating ball liquid level switch structure principle:

Floating ball type liquid level switch uses magnetic operation, no mechanical connection, simple and reliable operation. When the floating ball switch is floating float, the float drives the main body to move, and the magnet on the other end of the float will control the magnet on the switch action bar.

Technical advantages of floating ball liquid level switch: floating ball switch does not contain bellows, springs, seals and other components that cause failure. Instead, a straight float is used to drive the internal magnet of the switch, and the simple lever of the float switch makes the switch move instantaneously. Float cantilever Angle limit design, prevent float vertical.

In the closed metal or plastic tube, the design of one or more magnetic spring switch, and then the tube through one or more hollow floating ring with annular magnet inside, and the use of fixed ring, control the floating ball and magnetic spring switch in the relevant position, so that the floating ball in a certain range of up and down. The magnet in the floating ball is used to attract the contact of the reed switch, and the action of opening and closing is produced to control or indicate the liquid level.

UQZ floating ball liquid level switch features:

Control switch position can be customized according to user’s needs.

The reed switch does not require power supply, and the contact life can reach 2 million times.

All switch outlets are in the same junction box, the cost of external construction wiring is low.

Compared with other types of liquid level switches, the unit price of RF type z.UI is lower.

The protection level of the junction box is above IP-65.

PVDF, PP, PVC plastic material and SUS304, SUS316 metal material, so no matter acid alkali liquid, solvent or all kinds of fuel, there are suitable products can be used together.

The reed switch is completely isolated from the wire and liquid, so it can be used safely in high temperature and high pressure equipment.
