The DP2000/9000-S is a meter/controller for use with
pressure transducers and load cells which require
bridge excitation and preamplification of microvolt
signals. Deadload and tare adjustments make it
suitable for weighing applications. Like process meters,
it provides zero and span adjustments for direct
readout in engineering units. It can also be used as a
microvoltmeter with differential input. A universal
1/8 DIN case houses each meter. Choose any
combination of display type (LED or LCD), operating
power, input type and range, analog output, and digital or
control outputs.
Excitation Supply and Preamplifier
The DP2000/9000-S provides a constant-voltage
excitation supply, which is adjustable from 1 to 10V and
can drive up to 30 mA. It also provides a high-impedance
preamplifier, which is continuously adjustable so that
signal levels from ±2.0 to ±500 mV can produce the fullscale
display of ±1999 or ±9999 counts. At 10V excitation
and maximum gain, full-scale readout can be obtained
with strain-gauge sensitivity as low as 0.20 mV/V. An
active filter is provided for noise reduction.
Bridge Connection
Bridges can be connected by 4 or 6 wires. In 6-wire
connection, two lines sense the voltage applied to the
bridge and compensate for lead resistance.
Resolution and Accuracy Resolution for DP2000-S is one part in ±1999 counts,
or 0.05% of full scale. Resolution for DP9000-S is one
part in ±9999 counts, or 0.01% of full scale. Accuracy
is 99.9% of reading. The measurement is ratiometric
to reduce errors due to temperature and power-line
variations. The same internal reference controls the
meter gain and the excitation level.
