DAV – Anemometer with Measurement Head
The DAV anemometer is used for continuous measurement of air flow velocity in mine galleries, tunnels, corridors and for local signaling of flow fade. A high-brightness optical element signals danger at the entrance to the controlled area. The measuring head can be placed at a location up to 30 m away from the base unit.
The DAV anemometer is powered from the surface station via a telephone line. Data transmission is carried out along the power line. It is possible to connect up to four devices on one line.
