Digital Transducer Readouts

The E-405 programmable Smart Digital Indicator is a single-chan-

nel digital readout with a “99999” display. It sends a direct voltage

of 5 or 10 V to a load cell, pres sure or dis place ment transducer

or temperature trans duc er. The trans duc er then sends a millivolt

signal back to the readout, based on the amount of stress or strain

applied to the trans duc er. The E-405 then takes the millivolt signal

and converts it into engineering units based on the cal i bra tion fac-

tors stored in memory. The direct dis play of readings in engineer-

ing units is very convenient for the operator, in creas es productivity

and minimizes the po ten tial for re cord ing errors in the lab.

The E-405 has fast control responses (60 readings/sec), true peak

reading capability and an analog output that ac cu rate ly tracks the

signal input. It has an adaptive digital ﬁ lter that automatically se-

lects the best time con stant for minimum noise, and yet responds

rapidly to an actual change in signal level.

When purchased with a DGSI trans duc er, the E-405 is supplied

with a NIST Traceable Cer tiﬁ cate of Calibration. The front panel

allows user set-up and re-calibration by using push buttons.

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 indicators using 4-wire phone cable (also known as daisy

chaining). This feature allows the laboratory man ag er to custom-

ize the data acquisition from 1 to 31 channels and use the RS-485

to RS-232 con vert er to bring the data into the “Com Port” on his

com put er.

The E-405 can be customized for a wide variety of industry testing

tasks. If you have a spe cial ap pli ca tion, please call us to discuss

your requirements.

Have your proving rings, load cells, pressure gauges and

other measuring devices in the laboratory been cal i brat ed

recently? If not, give our calibration de part ment a call. They

will be glad to provide a quo ta tion for your cal i bra tion needs.
