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.
