The OMB-DBK9 is an eight-channel
RTD (resistance temperature device)
measurement card for OMEGA’s
OMB-LOGBOOK, OMB-DAQBOOK
and DAQBOARD 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 OMB-LOGBOOK,
OMB-DAQBOOK or DAQBOARD’s
internal 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.
