Circuit protection of float switch
| Features of Multi-point float switch |
| * Switch does not contact with the liquid directly, no abrasion and laceration. |
| * It is no power joint without any power supply and communicating signal treatment |
| with voltage contact, such as PLC. |
|
* Multi-point float switch is not impacted by foam, conductivity, medium constant,
|
| pressure, vacuum, temperature, evaporate,condensing liquid, bubble, boiling |
| effect and vibration. |
| * It can set several switch point (1 to 8) in a single fixation to realize multi- |
| point control and the location of every point can be custom made. |
| * All outlet wire of switch is concentrated in the junction box. Protection class |
| is IP65; construction is very simple and convenient; wiring cost is reduced. |
| * It is easy to install and use. Close and open once to regulate before use and no |
| need to maintain; overall performance is reliable. |
| * PP, PVDF, NYLON, CPVC, POM, PTFE materials; Max.operating temp. 105°C; Max. |
| operating pressure 5kg/cm². |
| * SUS 304/316L; Max.operating temp. 200°C; Max. operating pressure 60kg/cm². |
| * Top-Mounting. |
| * Mounting screw type have M8 ~ M16, 1/8"~1/2"PF / PT / BSP and etc. |
| * OEM / ODM and special specification are acceptable |
| * These switches are not effected by electrical interference. They can withstand to |
| chemicals, high temperatures and pressures if the correct material of Multi-point |
| float switch is selected by the customers. |
