LONGTEC Dynamic Weighing Transmitter - TR700LF

Available: In Stock
  • Order within
Features
  • Fits all resistive strain gauge load cells
  • High-precision m/V meter function; directly display the weighing m/V signal value
  • Control object non linear auto-tuning function
  • The advanced model control calculation can accurately predict the effect of each control value and adjust in advance
  • The incremental control strategy is adopted, and the control output does not fluctuate when the system switches between manual/automatic control
