Industrial lab-bench liquid level process control system paper-phase i

Abstract

In this paper, a lab-bench of a water level control system is fabricated. The fabricated water level system consists of two water tanks and one supply tank with similar dimensions. In the lab-bench, one variable speed drive (VSD), one 3-phase 0.75kW motor, two linear variable displacement transducer (LVDT), one paddle wheel i.e. a water flow sensor as well as CX-Programmer and CX-Designer are incorporated into the design. The first phase of the project is to monitor and manually control the work bench utilizing CX-Programmer (PLC) and VSD. PLC Omron is used to control the system, meanwhile CX-Designer is used to provide a human machine interface (HMI) for the lab-bench. The first phase of the water level system is completed successfully with the proposed workbench successfully monitored and the motor speed is varied manually via VSD. Initial analysis of the sensors utilized are presented for future references for the next phase of the project. The fabricated system is capable to operate manually and automatically through a monitoring system utilizing CX-Programmer.
