Data Acquisition Units
The Data Acquisition Unit (DAU) is used together
with an associated Radar Tank Gauge for local
readout and for connection of temperature sensors,
pressure transmitters, on/off switches etc when
more inputs/outputs are required than is available
in the RTG.
There are two versions of the Data Acquisition Unit,
the Slave DAU and the Independent DAU.
Slave Data Acquisition Unit DAU 2100
A Multiple Spot Thermometer (MST) with up to 14
temperature elements can be connected to the Slave
DAU. The unit is powered from, and communicates
through the Radar Tank Gauge to which it is
connected. The Slave DAU is intrinsically safe
using zener barriers on the Transmitter Interface
Card (TIC) in the Radar Tank Gauge.
The weatherproof box houses a printed circuit
board with a cable terminal for connection of the
temperature sensors, as well as the power and
communication cable. Cable inlet cable glands are
located at the bottom of the box.
