Encore Electronics, Inc.

INSTRUMENTATION AMPLIFIERS

Encore offers a line of single-ended and differential amplifiers with a wide range of features, from our compact DIN-rail mounted FL651 to the high common-mode-voltage Model 653 and the computer-controllable Model 643 and Model 650.

Our line of strain gage amplifiers can also be used as differential amplifiers, by not connecting the excitation source or bridge completion resistors.
