MODEL 632 STRAIN GAGE AMPLIFIER

Features

  • Auto-balancing
  • User-selectable bridge completion
  • Adjustable bridge excitation

Description

Up to sixteen channels of the Model 632 strain gage amplifiers can be mounted in the 19″W x 7″H x 20″ D rack adapter.  The integrated DC power supply is mounted at the rear of the rack to energize all 16 channels.  Each individual channel has its own on-board voltage regulator to provide the power required for the logic circuits, op-amps, and bridge excitation and ensures a load fault to any one module will not affect the other amplifiers.
