Christmas eve ceramic mug cup
P I D regulator regulator is proportional integral differential. Because it is proportional to the input current change (P), integral (I), differential (D) three kinds of operations, so called P I D regulator. Computational results are still to electrical signal output. Its principle is as shown in fig.. Deviation of the measured signal with a given value into the field effect regulator tube modulation, the DC signals into AC signals.
Then AC amplifier, the output transformer loss to the detection stage. And then filtered AC, DC United signal output 0 - 10 ma. The isolation transformer and rectifier demodulation amplifier output AC component, followed by PID operation loop feedback to the input. Thus, the PID regulation.
