商品説明
The OMET series is no longer available. Please see the OMB-DAQ54/55/56 series as
a possible alternative or contact our Data Acquisition Department.
The OMET-USB-73T is a USB
based data acquisition device
for thermocouple temperature
measurement. It is available with
8, 16 or 32 thermocouple inputs.
All standard thermocouples types
are supported, including J, K, E, T,
R, S, B, C and N. Onboard
programmable digital inputs and
outputs can be used to read the
status of external contacts or to
control relays or external contacts
in case of an event or alarm.
A screw-terminal panel equipped
with cold-junction compensation
is provided with each unit to
ensure accurate temperature
measurements.
This panel plugs into the
DB-25 connector(s) and the
screw-terminal connections
easily interface with thermocouple
wires. The OMET-USB-73T is the
perfect measurement tool for
users who want to measure
temperature, without high cost of
PLC or SCADA systems. Typical
applications include monitoring of
furnace, cold storage, computer
server rooms and environmental
monitoring to name but a few.
Software Support
The OMET-USB-73T includes
a comprehensive software suite.
A simple data logging program
is provided for users who want
collect data quickly and easily.
This program allows the user
to view thermocouple data on
screen and also save it to an
ASCII (.CSV) file. The data file
can be imported into Microsoft
Excel, Microsoft Word, or any
other compatible program for
viewing and analysis. This data
logger program works with
Windows 98 and later. Although
the OMET-USB-73T can support
sample rates of up to 200
readings per second, the logger
software only supports sample
rates of up to 10 readings per
second. For users who want to
create their own programs for a
more customized solution,
software libraries are provided for
most programming languages.
The languages supported include:
Visual C/C++ 6.0, Visual Basic 6.0.
Visual Studio.NET, Delphi, C++
Builder, GNU C/C++ for Windows
2000/XP. Drivers for the Linux 2.6
operating system are also
provided. The OMET-USB-73T can
also be used with other
third-party software, including
HPVEE, LabView, DasyLab
and TestPoint.
