Multi-point float level switch is designed and produced based on the principle of static magnetic field., The switch consists of a conduit inserted into the medium and an explosion-proof head for wiring. Non magnetic metal or plastic conduits are equipped with one or more magnetic spring switches (reed switches) as needed. For example, the two-point connecting rod float level switch has two control points, high and low; The three-point float level switch has three control points: high high position, high position, and low position; More control points can be set as needed to more flexibly control the liquid level. When the medium level gauge inside the container changes up and down, the floating ball on the conduit moves up and down with the liquid level change. The permanent magnet in the floating ball interacts with the reed switch in the conduit to control the suction or disconnection of the reed switch, generating an on-off switch signal (the switch signal can be set as multi-point, multi ball, and multi signal output), which can be used in conjunction with intermediate relays or AC contactors to control the opening and closing of equipment such as motors and water pumps.

Multi-point float level switches are characterized by strong load impact resistance, and one product can realize multi-point control. They are widely used in petroleum, chemical, electric power, light industry and pharmaceutical industries for controlling the level of media in various types of atmospheric and pressurized vessels.

Product Features

• Wide applicability and diverse installation forms.
• Multi point control, stable and reliable performance, strong anti-interference ability.
• Simple structure, easy installation, low maintenance cost, multiple materials to choose from, suitable for various occasions.
• The switch does not come into direct contact with the medium and can adapt to more working environments.
• Passive contacts do not require any power supply.
• The detection process has nothing to do with foam, conductivity, medium constant, pressure, vacuum, temperature, steam, condensate, bubbles, boiling effect and vibration, so it is not easily disturbed, and the measurement effect is better and more stable.
• A single float level switch can be set with multiple switch points (1-8) to achieve multi-point control, and the control points can be set according to user requirements.
• Polytetrafluoroethylene (PTFE) conduits and floats can prevent corrosion and can be used stably for a long time in corrosive liquids.
