X20AIA744Descrição:
- 2 full-bridge strain gauge inputs
- 5 kHz data output rate for both channels
- Independently configurable strain gauge factor and filter level for each of the 2 channels
This module works with 4-wire strain gauge load cells. The concept applied by the module requires compensation in the measurement system. This compensation eliminates the absolute uncertainty in the measurement circuit, such as component tolerances, effective bridge voltage or zero offset. The measurement precision refers to the absolute (compensated) value, which will only change as a result of changes in the operating temperature.
