Laboratory Data Acquisition
Data Acquisition and Reporting Software
We offer data acquisition systems for the soil testing laboratory:
 WinSAS, a Windows®-based serial acquisition system used in conjunction with E-405 Smart Digital Indicators which are modified for
serial port communication.
 A suite of reporting software to present the information in a way that conforms with the relevant ASTM standard.
 EZ-Daq 8-channel data acquisition system (see p.46).
WinSAS™ — Windows®-based collecting software
■ Increased production. Sensor readings are automatically
saved and available 24 / 7 if necessary.
■ Data accuracy: Automated data collection eliminates operator
errors.
■ Ease of use: Having digital readouts at the work station makes
it easy for the user to set up samples and visually monitor test
progress.
■ Flexibility to use the readouts without the PC if desired.
■ Easy to retrofit on older load frames.
WinSAS™ is a Windows®-based serial acquisition software used
in conjunction with E-405 Smart Digital Indicators which have
been modified for serial port communication. The software is preconfigured for common laboratory tests such as shear strength,
consolidation and penetration. However, the user can use the
software to collect data from a wide range of tests limited only by
the communication speed of the E-405 Smart Digital Indicators.
WinSAS™ gives the user the convenience of having digital indicators at the test stand with the ability of transferring the test data to
a standard ASCII text file. Multiple E-405 Smart Digital Indicators
may be linked together via a standard phone (RJ-45) cable to a
multiple plug connector. An RS-485/RS-232 converter is connected to the user’s computer via a standard DB-9 COMM port
connection.
Data Reduction and Reporting Software for Laboratory Soil
Testing
Our suite of Windows®-compatible software programs read data,
perform calculations and generate graphical and tabular output as
well as test reports conforming to the respective ASTM standard.
The various programs have a common rationale that makes it
easy to move from one program to another.
Principal features are:
 Windows® 98 through XP compatible.
 Powerful data base manager automatically saves input files by
project ID.
 Uses data from WinSAS™ output file.
 User-selectable engineering units for input and output.
 Software pre-configured to show company or agency name in
the output report.

WinSAS™ software permits the user to create a “test machine” by
grouping sensors from a user defined library to perform a specific
task, such as a CBR test. The sensor library contains the sensor type, maximum range, calibration, date and serial number.
WinSAS™ software includes a library of common soil tests from
which the user selects the type of test to be performed. The user
has the ability to change the suggested intervals on the fly. The
user can create custom logging profiles and intervals containing
up to 9999 data points.
Output of each channel assigned to the “test machine” is displayed with the elapsed time and reading. Also, any channel can
be graphically displayed with the sensor value plotted on the ordinate and the elapsed time on the abscissa or user-defined graphs
such as load versus deformation.

DURHAM GEO SLOPE INDICATOR
Digital Transducer Readouts
The E-405 programmable Smart Digital Indicator is a single-channel digital readout with a “99999” display. It sends a direct voltage
of 5 or 10 V to a load cell, pressure or displacement transducer
or temperature transducer. The transducer then sends a millivolt
signal back to the readout, based on the amount of stress or strain
applied to the transducer. The E-405 then takes the millivolt signal
and converts it into engineering units based on the calibration factors stored in memory. The direct display of readings in engineering units is very convenient for the operator, increases productivity
and minimizes the potential for recording errors in the lab.
The E-405 has fast control responses (60 readings/sec), true peak
reading capability and an analog output that accurately tracks the
signal input. It has an adaptive digital filter that automatically selects the best time constant for minimum noise, and yet responds
rapidly to an actual change in signal level.
When purchased with a DGSI transducer, the E-405 is supplied
with a NIST Traceable Certificate of Calibration. The front panel
allows user set-up and re-calibration by using push buttons.
Optional accessories include RS-232, Relay Board and Analog
“plug in” boards which allow the E-405 to output data to plotters or
computers. An RS-485 board is also available to connect up to
31 indicators using 4-wire phone cable (also known as daisy
chaining). This feature allows the laboratory manager to customize the data acquisition from 1 to 31 channels and use the RS-485
to RS-232 converter to bring the data into the “Com Port” on his
computer.
The E-405 can be customized for a wide variety of industry testing
tasks. If you have a special application, please call us to discuss
your requirements.

EZ-DAQ device showing, in this photograph, live data for three tests and
six sensors. Data from up to eight sensors may be acquired and displayed
simultaneously using the EZ-DAQ.
Description:
Now you can collect data easily from your current laboratory equipment with the EZ-DAQ System. EZ-DAQ is an
8-channel, 16-bit data acquisition unit* that is easy to use
and configure. The EZ-DAQ can perform locally all data
acquisition functions (sampling, signal conditioning, A/D
conversions), and when connected to a PC, can capture
data and display real-time graphs. Designed specifically for
the needs of today’s soils labs, the unit is flexible, reliable, and robust.
The bright, color screen is easy to read and has a high
performance CPU for ultra-fast screen refresh. The screen
is rugged for use in dirty, dusty conditions and incorporates a touch-panel for easy data entry. No openings to get
clogged or jammed.
In addition, connections for up to eight industry-standard
sensors are conveniently located on the rear of the unit.
These connections supply the common 10 V dc excitation
required by most of today’s sensors. Along with the excitation, the connections also handle the sensor return signals.
The flexibility designed into the EZ-DAQ System allows for
the return signals to be configured in mV, V, or mA, and a
multitude of ranges.
The EZ-DAQ-Soft software, which is included with the unit,
is highly configurable and simple to use. It gives the ability
to display up to eight active channels of data simultaneously on a PC. The system can support as many as six
individual tests with each test capable of having its own
sampling rate. The test files are saved as delimited text
which may be imported easily in a spreadsheet program or
simply opened as an ASCII text file.
Communication from the EZ-DAQ to the user's PC is done
with standard Ethernet protocol. Set up is uncomplicated
because it uses a static IP address.
* EZ-DAQ is not a data logger because it does not store data.
