SWP-VFD series PID controller is a kind of intelligent multifunctional secondary instrument, which can monitor, control, record and transmit the controlled parameter automatically according to the pre-set program. It is suitable for high precision multi-stage curve program heating/cooling control system (such as beer fermentation, kiln heating, etc.). According to the requirements of the production process, according to a certain curve for control, up to thirty-two sections of the curve on the control object for programming control, each section are using PID parameter setting control, so that the control is more professional and reliable.
Features: 1, respectively, with a PID control output and a transmission output, can be applied to a variety of measurement and control occasions.
2, can be divided into up to sixty-four sections of the curve on the control object programming control, each section are PID parameter setting control, so that the control is more professional and reliable.
3、It can realize automatic/manual switching without disturbance. When switching from manual to automatic, it adopts the approximation method of calculation, and has the function of switching limit, so as to realize the smooth switching of manual/automatic.
4、With a variety of curve control output function, it can realize the functions of curve control pause, curve control zero clearing, curve control step and so on.
5、Using dual-zone PID control, suppressing overshooting and improving control accuracy.
