Air Flow and Air Direction Sensors for Tunnels
For a tunnel project at Faroe-Islands (Hovstunnel, between Hov and Ravik) we have delivered a 3343 Air Flow Sensor and 3343 Air Direction Sensor from Aanderaa Data Instruments, together with 3429 Signal Converters for 4-20 mA output signals. These sensors are designed for control of ventilation fans in road tunnels, when the natural draught or wind is insufficient for proper ventilation. A 3017 Display Unit with engineering units and 4-20 mA output signals is also suitable as a local display and as output for connected PLC.
Location: The Faroe-Islands
System: AADI Air Flow and Direction Sensor with 4-20 mA Signal converters
Sensors: Air Flow and Air Direction
Data Handling: 4-20 mA signals to PLC
