Starting from Oct 1st 2017, DP2000/9000 Series will be discontinued. As a possible substitute, please check out the or for details.

The DP2000/9000-S is a meter/controller for use withpressure transducers and load cells which requirebridge excitation and preamplification of microvoltsignals. Deadload and tare adjustments make itsuitable for weighing applications. Like process meters,it provides zero and span adjustments for directreadout in engineering units. It can also be used as amicrovoltmeter with differential input. A universal1/8 DIN case houses each meter. Choose anycombination of display type (LED or LCD), operatingpower, input type and range, analog output, and digital orcontrol outputs.

Excitation Supply and Preamplifier
The DP2000/9000-S provides a constant-voltageexcitation supply, which is adjustable from 1 to 10V andcan drive up to 30 mA. It also provides a high-impedancepreamplifier, which is continuously adjustable so thatsignal levels from ±2.0 to ±500 mV can produce the fullscaledisplay of ±1999 or ±9999 counts. At 10V excitationand maximum gain, full-scale readout can be obtainedwith strain-gauge sensitivity as low as 0.20 mV/V. Anactive filter is provided for noise reduction.

Bridge Connection
Bridges can be connected by 4 or 6 wires. In 6-wireconnection, two lines sense the voltage applied to thebridge 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 onepart in ±9999 counts, or 0.01% of full scale. Accuracyis 99.9% of reading. The measurement is ratiometricto reduce errors due to temperature and power-linevariations. The same internal reference controls themeter gain and the excitation level.
