The OMB-DAQTEMP series has been discontinued. Please see the OMB-DAQ-TC-RACK as a possible alternative or contact our Application Engineering department for details.
The OMB-DAQTEMP-14A data
acquisition card provides a total
hardware/software/signal
conditioning solution for highaccuracy,
high speed temperature,
voltage, frequency, and pulse
counting measurements, plus digital
I/O and analog output.
A diversified software is included
with the OMB-DAQTEMP-14A, including
DaqView software, plus drivers for
DASYLab, LabView, and Windowsbased
languages including Visual
Basic and C++.
OMB-DAQTEMP-14A hardware is
comprised of a plug-n-play PCI
board, 3 ft cable, and a screw
terminal/signal conditioning pod.
Cold-junction compensation is
built-in to the OMB-DAQTEMP-14A,
providing highly accurate
thermocouple measurements, with
channel-to-channel variation and
noise typically less than 0.2°C,
and absolute accuracy typically
better than 1.0°C.
This is
accomplished by having a separate
low-noise, bandwidth-limited
amplifier per thermocouple channel.
OMB-DAQTEMP-14A provides
14 thermocouple input
channels. All power for the
OMB-DAQTEMP-14A is derived from the
PC, so there is no need for external
power supplies or transformers.
In addition to thermocouple inputs,
OMB-DAQTEMP-14A also provides 7
differential voltage input channels,
with 16 bit resolution and
programmable full scale input
ranges from +156 mV to +10 V.
The 4 frequency input channels can
measure frequency or count pulses
up to 10 MHz. Two timer output
channels are capable of generating
square outputs up to 1 MHz.
Twenty four digital I/O lines are also
included, which can be programmed
in 8 bit groups as either inputs or
outputs.
The 16 bit/100K Hz analog
outputs can be used to generate
waveforms, with a virtually infinite
waveform output length possible
from PC memory.
All inputs and outputs are accessed
via convenient screw terminals
located on the signal conditioning
pod. The cover of the signal
conditioning pod is easily removable
to gain access the screw terminals
for signal connections.
DAQVIEW SOFTWARE
The included DaqView software
allows you to verify signal
connections, acquire and save data
to disk, and graphically view realtime
data within moments of taking
your installing your system. Easily
set up all your hardware,
acquisition, and display parameters,
without programming, via a simple
spreadsheet-style screen. DaqView
is a full featured acquisition and
display application that provides all
the functionality you’ll need for
many datalogging applications.
SWD-DAQVIEW-XL
DaqViewXL is an optional Excel
add-in that provides complete data
acquisition functionality. Seamlessly
integrated into Excel’s tool palette,
DaqViewXL provides you with the
same comprehensive acquisition
and display capabilities as
DaqView. Excel is an ideal tool for
test engineers because it provides a
variety of graph and charting
functions for presenting data in a
graphical format, as well as
mathematical and analysis functions
such as FFTs. Excel’s ability to
retrieve and manipulate previously
acquired data in a spreadsheet
format and DaqViewXL’s advanced
data acquisition functions form a
comprehensive data acquisition
solution.
