    T818

    Parameter details

    application

    T818 series self-tuning expert PID valve control special instrument adopts many advanced technologies, has AC100 ~ 240V wide range input switching power supply, the input adopts digital correction and self calibration technology, the measurement is accurate and stable, and the measurement error caused by temperature drift and time drift is eliminated. The instrument adopts surface mounting technology, multiple protection and isolation design, with strong anti-interference ability and good reliability.


    function

    *Three window display function is used to display the measured value, given value and valve feedback value, which makes the instrument data display more clear and intuitive.

    *Zero and full correction, cold junction compensation, digital filtering, sensor fault processing, communication interface, 60 segment broken line input correction, program control, switch input, switch output and other extended functions.

    *Multi type input with different input signals (thermocouple / thermal resistance / linear voltage, linear current / linear resistance).

    *With / without feedback function can be set, self calibration valve position.

    *PID intelligent regulation algorithm, accurate and stable control, no overshoot, with high-precision self-tuning (at) function.
