BAGGI BA-DALS
Data Acquisition and Logging System
The BAGGI BA-DALS complements the BAGGI
BASE® Instruments Series. They are the result of
combining the latest state-of-the-art-technology with
over 50 years of industry experience.
The BA-DALS is a Data Acquisition and Logging
System that meets all the industry signals and
protocols
standards. It can act as
a SCADA system,
providing
closed
loop control functions. Upon request,
it is available for
operation in an explosive atmosphere
(ATEX)
environment. It offers an
outstanding flexibility and can be easily customized
according to customer’s requirements due to:
The modular and replaceable building blocks
used for interfacing the I/O signals
The capability of easily updating and upgrading the software that operates and controls the whole
system.
The system is controlled by an embedded computer
running the BASE® application software.
The figure shows an ATEX certified version, contained
within a Stainless Steel 316L enclosure provided with
a protective air purge system and a Vortex cooler
(connected to the plant instrument air). Magnetic push
buttons allow controlling the system without opening
the cabinet.
ATEX compliance:
- II 2 G Ex px II T6
- II 3 G Ex pz II T6

Alarms package: it allows to associate filters
and alarm thresholds to each of the input signals and activating a related output signal.
Signal processing (mathematical) package: to
derive measurement results from raw sensor
data, e.g. the calculation of flow rate by
means of differential pressure measurements
in a Venturi tube, corrected by temperature
measurements.

A watch-dog device polls continuously the health
state of the computer and the pressure within the
pressurized enclosure (Atex version).
The analog and digital input/output signals are
bundled into independent specialized hardware
modules, contained in the same enclosure as the
computer. Examples of modules are:
• Analog input signals
• Analog output signals (0/4…20 mA)
• Opto-isolated digital inputs
• Digital outputs
• Thermocouple inputs (type J, K, R, S, T, E, B,
N)
• RTD inputs (Pt-100, Pt-500, Pt-1000, Ni-100)
3, 4 wire
• Resistance up to 15 K
• Strain gauge input

The applications are coded using a high level Object
Oriented Language. The main software packages are:
• GUI package: Graphical User Interface for inputting commands via menu driven interfaces and
displaying the measurements in tabular and
graphic format.
• Data Base package: the data are archived and
exported in standard CSV format.
• PLC package: this package allows executing all
the functions of a Programmable Logic Controller
for controlling actuators and closed loop operation.
