• 2 full-bridge strain gauge inputs

• Data output rate configurable from 2.5 Hz to 7.5 kHz

The module is equipped with 2 inputs for evaluating full-bridge strain gauges and works with both 4-wire and 6-wire strain gauge load cells. The concept applied by the module requires calibration in the measurement system. This calibration compensates or eliminates the absolute inaccuracies in the measurement circuit ( e.g. component tolerances, effective bridge voltage or zero offset). The measuring accuracy related to an absolute (calibrated) value only changes due to the negative influence of a change in the operating temperature.
