The unit is powered from, and communicatesthrough the Radar Tank Gauge to which it isconnected. The Slave DAU is intrinsically safeusing zener barriers on the Transmitter InterfaceCard (TIC) in the Radar Tank Gauge.The weatherproof box houses a printed circuitboard with a cable terminal for connection of thetemperature sensors, as well as the power andcommunication cable. Cable inlet cable glands arelocated at the bottom of the box.The Slave Data Acquisition Unit withLocal Readout Display mounted at thefoot of a tank.LCD display forlocal readout0.28 m (11 in.)0.23 m (9 in.)Data Acquisition Unit Type DAU 2100Hazardous Location Class I Group Cand D.
