Parallel plate interceptor (PPI), Corrugated plate interceptors (CPI) are Plate coalescers. Plate coalescers are skim tanks or vessels that use plates used to increase the process of gravity separation. Various forms of coalescer plate have been found. Parallel Plate Interceptor (PPI) The first…

The instruments used to measure the physical and electrical quantities are known as measuring instruments. The measuring instruments may be classified as follows: Absolute instrument & Secondary instruments: Absolute instrument measures the process variable directly from the process without the use of conversion. Such…

Why sensors are used in process industry? Automation devices used for the realization of control techniques from a process such as hardware, PLC software or microcontroller can only run well if the required process data can be obtained validly, for example information such…

Open loop control system: the process in the system where one or several input variables affect other output variables as a result of the law affecting each other from a system. Control is characterized by an “open-loop” sequence of actions or control…

Advantages of the Hydraulic system:   When compared to the mechanical power method has a weakness in the placement of the transmission power position. It is different with hydraulic power hydraulic power lines can be placed in any place. Regardless of the…

What is DDL? DDL HART equipment description language extends mutual operation (interoperability) exceeds the Universal commands and Common Practice commands. A slave equipment manufacturer uses DDL to create one software file with all relevant equipment characteristics, so a DDL-capable host can communicate…

The automated system (Automation System AS) is a PC computer-based workstation device and microcomputer control modules with distributed processing capability (distributed processing capability) and allows the addition of input/output functions and the development of control/processing functions. Components of automated system: The automatic…

It is a data communication that aims to reduce or prevent failure in several loops. This results in the failure of a loop to affect the other control loops. The use of Fieldbus also functions as savings on cable routing because the…

Understanding the process is the basis for getting a well-designed control node. The sensors must be in the right location and the valves of the correct size and position. In general, for the best node control, dynamic controller gain must be as…
