Descrição:
  • 1 full-bridge strain gauge input
  • Bridge voltage 10 VDC
  • Data output rate configurable from 0.1 Hz to 7.5 kHz
  • Special operating modes (synchronous mode and multisampling)
  • Configurable filter level

This module works with both 4-wire and 6-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 point offset. The measurement precision refers to the absolute (compensated) value, which will only change as a result of changes in the operating temperature.
