Description
GEX swimmer switch In the anti -balance version with ATEX (EX) approval, it is designed to cooperate with pumps performed by ex in water and sewage media, also with an admixture of diesel oils, hydrocarbons, engine oils, machine, kitchen and other. The body's body was filled with injection -free polyurethane with closed cells, which completely surrounds the control switch and eliminates the air supply to the interior.
Composition of the GEX swimmer switch
| Element | Description |
|---|---|
| Case | Polyethylene, intended for work in an environment with hydrocarbons |
| Internal weight | Determines the center of rotation (center of gravity) in the immediate vicinity of the cable connection |
| Contacts | Control electric switch (max. 21.4 mA / 13 V) |
| Cable | A special blue cable to work in a hydrocarbon environment |
| Filling | Injection polyurethane with closed cells, non -surgoscopic |
Note (security): The regulator must be connected to the sparkful power supply circuit. It is recommended to use security module EMS-EX with ATEX certificate, dedicated to Floatthat in the anti -balance. In order to avoid the accumulation of electrostatic charges on the housing, the device should be used to control the level of liquid in tanks, tanks, windows, etc., while ensuring low liquid flow speed.
