In today's competitive environment, process industry companies are focused on two key objectives: profitability and delivering value to customers. However, these objectives are often disparate goals ...

Figure 1. Shown is a graphical representation of the method of principal component analysis (PCA). Each principal component summarizes key features of the data while filtering out process noise. Â ...

In past columns, I've written about measurement of the key process variables in extrusion: Melt temperature, melt pressure and motor load . . . the vital signs. However, I shouldn't assume that all of ...

Increasingly tight tolerances and rigorous demands for quality are forcing chipmakers and equipment manufacturers to ferret out minor process variances, which can create significant anomalies in ...

In this article, as in industry, advanced process control (APC) refers primarily to multi-variable control. Multivariable control means adjusting multiple single-loop controllers in unison, to meet ...

The most important factors involved during sintering process are temperature, time and furnace atmosphere. The influence of these factors on the sintering process is described below:5 Sintering ...

The drum surface roughness determines the number of contact points per unit area. The greater the number of contact points, the greater the heat transfer. Typically, a 1 microinch mirror finish is ...

New process device profiles have been added by ODVA to the EtherNet/IP specification to provide end users with another tool to help optimize plant operations. According to ODVA, the new process device ...
