DGSI. Durham Geo Slope Indicator

Digital Transducer Readout

The E-405 programmable Smart Digital Indicator is a single-channel digital readout with a "99999" display. It sends a direct voltage of 5 or 10 V to a load cell, pressure or displacement transducer, or temperature transducer. The transducer then sends a millivolt signal back to the readout, based on the amount of stress or strain applied to the transducer. The E-405 then takes the millivolt signal and converts it into engineering units based on the calibration factors stored in memory. The direct display of readings in engineering units is very convenient for the operator, increases productivity, and minimize the potential for recording errors in the lab.

The E-405 has fast control responses (60 readings/sec), true peak reading capability, and an analog output that accurately tracks the signal input. It has an adaptive digital filter that automatically selects the best time constant for minimum noise, and yet responds rapidly to an actual change in signal level.

When purchased with a Durham Geo transducer, the E-405 is supplied with a NIST Traceable Certificate of Calibration. The front panel allows user set-up and re-calibration by push buttons. The software which accompanies the RS-232 and RS-485 options, allows for recalibration through a computer.

Optional accessories include RS-232, Relay Board, and Analog "plug in" boards which allow the E-405 to output data to plotters or computers. An RS-485 board is also available to connect up to 31 meters using 4-wire phone cable (also known as daisy chaining). This feature allows the laboratory manager customize his data acquisition from 1 to 31 channels, and use the optional RS-485 to RS-232 converter to bring the data into the "Com Port" on his computer.

The E-405 can be customized for a great variety of industrial and testing industry tasks. If you have a special application, please call us to discuss your requirements.

The example on the right shows three E-405 Readouts (connected to a load cell as well as alinear displacement and pore pressure transducers) on a permeability / triaxial cell.
