MODEL 633 STRAIN GAGE AMPLIFIER

The Model 633 is a high performance strain gage amplifier that integrates into Encore’s 19″ GPSC instrumentation rack.  Each rack can accommodate up to eight modules (16 channels).  Modules are available for strain, F/V, charge, accelerometer, proximitor, DC signal, and LVDT signal conditioning.  The integrated AC power supply provides the required  DC voltages to operate  each of the modules.  The Model 633 offers high performance and expandability at a competitive price.
