PRESSURE CONTROL TRAINER 3414-A
The pressure inside pressure tank is sensed by pressure sensor with transmitter. A pneumatic control valve adjusts compressed air flow from the tank. The process parameter (pressure) is controlled through computer or up controller by manipulating the control valve. These units along with necessary piping are fitted on support housing designed for tabletop mounting.

CASCADE CONTROL TRAINER 3415
The process setup consists of supply water tank fitted with pump for water tank fitted with pump for water circulation. Level sensor is fitted on transparent process tank. The water flow to the tank is sensed with orifice meter. The water flow (secondary loop) to the process is controlled by pneumatic control valve to maintain the level (primary loop) under cascade control logic. The process parameter is controlled through computer. These units along with necessary piping are fitted on support housing designed for tabletop mounting.
TYPE: Computer controlled setup (DDC model)
