UJI KINERJA ALAT PENGENDALI TEKANAN MELALUI PERSONAL KOMPUTER MENGGUNAKAN APLIKASI DELPHI 7 (Performance Test of Pressure Control Apparatus with Personal Computer using Delphi 7 Application)

Abstract

Process control system is a joint work between process control equipment and instrumentation electronics. In a pressure control system, sensing element (sensor) is very important in the measurement or measurement activities. An automatic control system in a work process serves to control the process without any human intervention. While the data obtained will be converted into information by a micro controller as an interface to visualize on a computer on. Pressure control device of this thesis use the software to program as Delphi 7. Delphi 7 is a Windows-based programming language that provides the facility of making visual applications such as Visual Basic. Delphi 7 provides convenience in using the program code, quick compilation, the use of multiple unit files for modular programming, software development, design patterns are interesting and reinforced with structured programming language Object Pascal programming language. Expected to the program Delphi 7, the results are more informative. Not just a number but has shaped graph. So that the results can also be seen in the response that occurs in the process.
