The OMB-DBK9 is an eight-channel
RTD (resistance temperature device)
measurement card for OMEGA’s
OMB-LOGBOOK and
OMB-DAQBOARD-2000 Series
data acquisition systems. The
OMB-DBK9 supports up to 8
channels of 3- or 4-wire RTD’s with
resistances of 100, 500, or 1000
Ohm. RTD-type selection is made
via a jumper on the card that
configures all 8 channels.
Excitation Sources
The OMB-DBK9 provides bias for
the RTD with eight constant current
sources derived from the OMBLOGBOOK or OMB-DAQBOARD2000 Series Sinternal power supply.
Input Amplifier
The OMB-DBK9’s instrumentation
amplifier provides both a high and
low resolution gain for each of the
standard RTD types.
Software
Included software auto-matically
controls the OMB-DBK9 to
effortlessly supply you with correct
temperature measurements. You
need only indicate which RTD type is
attached to each channel. Thereafter,
whenever a measurement is
requested from a channel, the entire
measurement procedure including
linearization occurs automatically.
The data acquisition systems are
shipped with several Windows
applications including a datalogging
application that allows you to acquire
RTD’s and other measurements via
a spreadsheet-style user interface.
Also shipped is eZ-PostView, a
post-acquisition application that
permits you to display acquired
data previously saved to a file.
