The anti-corrosion float level switch is designed and produced based on the principle of magnetic field. The liquid level switch consists of a conduit inserted into the medium and an explosion-proof meter head for wiring. When the liquid level in the container changes, the float on the conduit moves up and down with the change of the liquid level. The permanent magnet in the float acts on the reed switch in the conduit to control the attraction or disconnection of the reed switch, generating an on-off switch signal, thereby controlling the opening and closing of equipment such as motors and water pumps.

The conduit of the anti-corrosion float level switch is wrapped with polytetrafluoroethylene (PTFE), and the surface of the float is sprayed with polytetrafluoroethylene (PTFE). Polytetrafluoroethylene (PTFE) has excellent chemical stability and corrosion resistance. This level switch can be used for level measurement work with corrosive media. It has a wide range of applications in the control of the liquid level of media in containers in the chemical, petrochemical, oil refining, pharmaceutical, pesticide, chemical fiber, food, beverage and other industries.

Product Features

• Wide applicability and diverse installation forms.
• Polytetrafluoroethylene (PTFE) conduits and floats can prevent corrosion and can be used stably for a long time in corrosive liquids.
• 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.
