The Austdac Air Speed Monitor, Type AASM1, is used to measure wind speed primarily in mining situations. The AASM1 comes in two parts, the Air Speed Monitor 1 Anemometer, Type SCGR1 and the 2 Channel Frequency Transmitter, Type SILBUS-TX2F. The SCGR1 measures the air speed while the SILBUS-TX2F processes that information and can activate relays, strobes or transmit the information via SILBUS.
