PVDF (TeflonStrong Acid & alkali / Corrosion Resistance 
Ball float type Liquid level Switch/Controller/Sensor
liquid level switch - Picture 3 of 6
liquid level switch - Picture 2 of 6
The corrosion resistance of PVDF is much stronger than that of PP material!

Material: Polyvinylidene Fluoride
Temperature resistance:  -10 ~ 120℃ (14 ~ 248)
Pressure Resistance: 0.2MPa
Feature: Strong acid & alkali resistance,strong corrosion resistance              
Withstand voltage:  0 ~ 120V/AC/DC :  10W
                                ~ 240V/AC/DC :  50W
Note: Don't overload! otherwise, it will be broken and burned out!
Application: Chemical industrial liquids with strong acid and alkali corrosion, such as electroplating solutions and acid pickling tanks!
 
Normal open/close convert: Remove the plastic card, flip the floating ball,
                                            then switch normal open / normal close mode!
