Digital display instrument
Intelligent PID regulator

The intelligent PID regulator is used in conjunction with various sensors and transmitters to realize the measurement and display of temperature, pressure, liquid level, capacity, force and other physical quantities. The intelligent PID regulator and various actuators are used for electric heating equipment and electromagnetic, Electric and pneumatic valves perform PID adjustment and control, alarm control, data acquisition and recording.

Features

● Universal input function
● Auto calibration and manual calibration function
● Manual / automatic disturbance-free switching function
● Can choose to adapt to the positive or negative effect of heating or cooling
● Control output signal limit
● The intelligent PID regulator uses a combination of fuzzy control theory and traditional PID control to make the control process have the advantages of fast response, small overshoot, and high steady-state accuracy. It has obvious control over large pure lag objects that are difficult to control with conventional PID effect
Intelligent PID regulator adds 30-segment program control function
