MODEL 632 STRAIN GAGE AMPLIFIER ASSEMBLY
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.
