DESCRIPTION:

1 full bridge strain gauge input
Data output rate adjustable from 0.1 Hz to 7.5 kHz
Special operating modes (synchronous mode and multiple sampling)
Filter level adjustable

The module works with both 4-wire and 6-wire strain gauge cells. The concept of the module requires an adjustment in the measuring system. This adjustment compensates or eliminates the absolute inaccuracies in the measuring circuit (such as e.g.: component tolerances, effective bridge voltage or zero point shift). The measurement accuracy based on an absolute (adjusted) value only changes due to the negative influence of a change in the operating temperature.
