Process Control Training Plant Model PCT 029
Sci-tech Process Control Training Plant Model PCT 029 offers the complete closed loop of a filling level control system. The concept and equipment permit the experimental examination of all important problems found in control technology. A transparent plastic cylinder is used as the filling level tank, into which a centrifugal pump moves water from a tank with sight glass. The filling level is recorded by a pressure transducer, which permits the further processing of the measured value by emitting a standardized current signal. The actuator in the circuit is a pneumatic control valve. The switch box contains an industrial controller, a chart recorder and all required electrical measuring equipment. The entire trainer is mounted on a movable frame with four castors.
