Reed level gauge

The UQZ floating ball reed level gauge switch consists of three parts: a magnetic levitation ball, a sensor, and a switch. When the magnetic levitation ball floats up and down along the guide tube as the liquid level changes, the magnetic steel inside the levitation ball attracts the reed tube at the corresponding position in the sensor, causing a change in the total resistance (or voltage) of the sensor.

The UQZ floating ball reed level gauge switch consists of three parts: a magnetic levitation ball, a sensor, and a switch. When the magnetic levitation ball floats up and down along the guide tube as the liquid level changes, the magnetic steel inside the levitation ball attracts the reed tube at the corresponding position in the sensor, causing a change in the total resistance (or voltage) of the sensor. Then, the switch outputs the resistance (or voltage) signal after the change to the upper and lower switch signals, achieving the opening and closing of the infusion pump; Upper and lower limit alarms can be set on the display to achieve positional control of the liquid level.

Float type liquid level switches are specifically used for liquid level detection, remote transmission of on-site indication signals, and liquid level alarms in various small and medium-sized atmospheric and pressurized liquid storage tanks. They are suitable for various sanitary, toxic, corrosive media, and explosive gas hazardous areas. There are multiple installation forms suitable for various types of containers.

Float type liquid level switch is suitable for controlling pump operation to maintain liquid level; Automatic loading and unloading of control tanks; Control liquid level or supply signals, such as oil tanks, automatic cleaning systems, hydraulic tanks, low-pressure boilers, and sewage treatment systems.

The structural principle of UQZ floating ball level switch:

The float type liquid level switch operates with magnetic force and has no mechanical connectors, making it simple and reliable to operate. When the float switch is tested by the floating float of the medium, the float drives the main body to move, and at the same time, the magnet on the other end of the float will control the magnet on the switch action rod.

The technical advantages of a float type liquid level switch: The float switch does not contain components such as bellows, springs, and seals that cause faults to occur. But 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 act instantly. The cantilever angle limit design of the float prevents the float from being vertical.

Design one or more magnetic spring switches inside a closed metal or plastic tube, and then pass the tube through one or more hollow floating rings with ring shaped magnets inside. Use a fixed ring to control the floating ball and magnetic spring switch in the relevant positions, so that the floating ball can float up and down within a certain range. Use the magnet inside the float to attract the contact point of the magnetic spring switch, generate opening and closing actions, and control or indicate the liquid level.

Characteristics of UQZ Floating Ball Level Switch:

The position of the control switch can be customized according to the user's needs.

The use of magnetic spring switches does not require power supply, and the contact life can reach 2 million times.

All switch outgoing lines are in the same junction box, and the external construction wiring cost is low.

Compared to other forms of liquid level switches, the RF type has a lower unit price for multiple switch control points.

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

There are PVDF, PP, PVC plastic materials, as well as SUS304 and SUS316 metal materials, so suitable products can be used in combination with various acids, solvents, or fuels.

The magnetic spring switch is completely isolated from the liquid from the wire, so it can also be safely used on high temperature and high voltage equipment.
