Catalog excerpts
• True Wheatstone bridge circuitry • Simulates quarter, half, and full-bridge • 12 position preset range • Quarter-bridge strain range direct reading: • Half and Full-bridge strain range direct reading: • Reversing switch for plus and minus calibration • High precision resistors used throughout to ensure excellent stability • Strain Indicator Calibrator • Stress Indicator Calibrator • Material elasticity Indicator Calibrator • Load Cell Indicator Calibrator • Micro-Resistance Indicator Calibrator • Load Cell Signal Conditioning Calibrator • Foil Strain Gage Signal Conditioning Calibrator • Semiconductor Strain Gage Signal Conditioning The Model AB calibrator is a Wheatstone bridge and generates a true change of resistance in It simulates the actual behavior of a strain gage in negative strain calibrator based on the Wheatstone bridge principle requires stable components. Multiple ultra-stable and hi-stable precision resistors are used in the Model AB calibrator to provide the stability, repeatability and accuracy required in a laboratory strain gages instrument.
