FEMA Smart SN | Electronic Pressure Transducers | -1...+1 to 0-40 bar, G1/2
FEMA Smart SN microprocessor-supported transducers measure relative pressure in ranges from -1...+1 bar up to 0-40 bar. They install directly in the pressure line through a G1/2 external thread and are aimed at mechanical engineering, supply engineering, environmental technology and HVAC. Versions exist for 2-wire, 3-wire and alternating-current operation, and all 2-wire versions are SIL 2 approved.
Key features
- Keyboard and graphic display for entering switching points
- Restore function, manual zero and 4-digit locking code
- Warning display for sensor fault, overload and overheating
- 100 ms cycle time; DMW surge reducer recommended for short surges
- Ambient range -20 to 80 °C
