Omega Products OMB-DBK16 User Manual
The OMB-DBK16, $649, strain-gage
expansion card, shown smaller than acutal size
⻬ Provides 2 Channels
of Strain-Gage Inputs
⻬ Accommodates Most
Bridge Type Sensors,
Including 4-Element
Full Bridges
A two-channel strain-gage expansion
card for OMEGA’s OMB-LOGBOOK
and OMB-DAQBOARD-2000 Series
data acquisition systems. The
OMB-DBK16 is a general-purpose
card that accommodates the
connection of most strain-gage types,
from single-element quarter-bridges
to 4-element full bridges. The
OMB-DBK16 also includes provisions
for bridge completion resistors and
provides four adjustments on each
of its two channels. You can adjust
excitation voltage, input gain, offset
nulling and output scaling. Up to
128 OMB-DBK16 boards can be
connected to one OMB-LOGBOOK
or OMB-DAQBOARD-2000 Series.
For applications of 5 or more
channels, use the 8-channel
OMB-DBK43A strain-gage module.
Excitation Regulator
The OMB-DBK16 accepts usersupplied excitation input voltage
from 12 to 16 V on each channel. Its
on-board excitation regulator can be
adjusted from 1.5 to 10.5 Vdc.
Excitation Sources
The 12 to 16 Vdc external excitation
source required by the OMB-DBK16
can be supplied by the OMB-DBK30A
rechargeable battery/excitation
module or by a user-supplied source.
Coupling & Filtering
Each channel of the OMB-DBK16
offers switch-selectable AC or DC
coupling between the input amplifier
circuits and the filter stages. A
selectable three-pole low-pass filter
with a cus-tomizable cutoff
frequency is also provided.
