                        EPDM | FPM
- 1 to 4 switching points
- diaphragm pressure switch without medium contact
- pressure transmission by air
- low switching pressure
- corrosion resistant materials
- for unpressurised containers and pits
- process automation, e.g. as an optical or acoustic signal
- potential-free switching contacts
- does not require a power supply
