配置和组成 DAQ F/T SYSTEM

Configurations
DAQ F/T Systems come in one of two configurations
depending on the size of the transducer.
Internal Interface Board Configuration: Transducer
with internal interface board electronics (Gamma and
larger), transducer cable, power supply box, power
supply cable, data acquisition board, and user computer.
External Interface Board Configuration: Transducer
without electronics (Nano and Mini Series), interface
power supply box, power supply cable, data acquisition
board, and user computer.
Components
Transducer: The transducer senses applied loading with
six degrees of freedom (Fx, Fy, Fz, Tx, Ty, and Tz). Gamma
and larger transducer models have the interface board
inside the transducer while Nano and Mini transducer
models require the interface board to be housed in an
interface power supply box (IFPS). ATI software must be
used to convert the transducer’s uncalibrated ouput to
calibrated values.
Transducer Cable: For our Nano and Mini transducer
models, the transducer cable is integral to the transducer.
For other transducers the transducer cable is attached
with a connector. The transducer cable is a long-life
flexible cable specially designed for noise immunity.
This durable cable protects the transducer signals from
electrical fields and mechanical stress.
Interface Board: The interface board electronics receive
transducer gage signals and converts them to readable
DAQ card signals using noise immunity technology.
Each interface board is calibrated to mate to a specific
transducer. The interface board is mounted within the
Gamma and larger transducer models and is located in
the interface power supply box (IFPS or IFPSMC) for
the Nano and Mini transducer models. Since transducer
output is uncalibrated, ATl software must be used to
produce calibrated output.
Power Supply: The power supply converts readily
available 5 volts from the PC through the DAQ card
connection to regulated power used by the transducer.
The power supply is mounted in a small box that
connects to the transducer cable on one end and to the
data acquisition card on the other When not mounted
on the transducer, the interface board is mated directly
to the power supply.
Power Supply Cable: The power supply cable conducts
5 volt power to the power supply box or interface power
supply box and transmits the transducer signals to the
data acquisition card. The cable is a flexible long-life
design with special noise immunity features.
Data Acquisition (DAQ) Card: The data acquisition card
plugs into your PC, receives the analog transducer
signals via the power supply cable and (with ATl software
on your computer) converts them into data to be used
by computer programs. Our data acquisition cards are
available in a wide variety of configurations and supply
power to the F/T system. In some cases, you can use
an existing data acquisition system.
DAQ Multiple Transducer IFPSMC Box (optional):
This version of our standard Interface Power Supply
Box provides power and signal amplification/conditioning
for up to six transducers. It connects to an 80-channel
DAQ card usings standard off-the-shelf cables. The
IFPSMC is available only for transducers that do not
have internal interface board electronics.
Multiple Transducer IFPSMC Box
DAQ F/T Dual Gain (optional): A transducer may have
two calibrations which allows switching between higher-
resolution calibration and a larger-range calibration. The
larger-range calibration must be exactly twice the
higher-resolution calibration. Switching calibrations is as
easy as just loading the other calibration.
Note:
ATI DAQ systems perform best when used with the cabling and
data acquisition hardware we supply. The demanding nature of
precision analog signals makes it likely that other configurations
will not perform optimally. The use of breakout boxes, unshielded
cables and wires that are not twisted pair is discouraged as
their use will result in increased noise.
