  • A PLC or programmable controller is a computer based solid state device that controls industrial equipment and processes. Initially designed to perform the logic functions executed by relays, drum switches and mechanical timer/counters, it has been extended to analog control as well. A typical PLC system consists of a processor and an input/output system all mounted in a rack like system. The PLC system is a cost effective solution for applications with a high ratio of digital to analog points in a system.

  • This work is an extension to the earlier publication Instrumentation Fundamentals for Process Control (2001) in which the basics of instrumentation were given along with some applications of instruments and control systems to real processes. Because the present work is an extension of this latter aspect, it is therefore confined mainly to the techniques of applying instrumentation and control systems to manipulate the process to give the desired results.

  • The LabVIEW Tutorial contains the information you need to get started with the Laboratory Virtual Instrument Engineering Workbench (LabVIEW) software package. LabVIEW simplifies scientific computation, process control, and test and measurement applications, and you can also use it for a wide variety of other programming applications. This manual gives you an overview of the fundamental concepts of LabVIEW, and includes lessons to teach you what you need to know to build your own virtual instruments (VIs) as quickly as possible. This manual does not explain every LabVIEW feature.

  • Analysis and abatement of air pollution involve a variety of technical disciplines. Formation of the most prevalent pollutants occurs during the combustion process, a tightly coupled system involving fluid flow, mass and energy transport, and chemical kinetics. Its complexity is exemplified by the fact that, in many respects, the simplest hydrocarbon combustion, the methane-oxygen flame, has been quantitatively modeled only within the last several years.

  • Geobiology is a highly cross-disciplinary field that explores the present and past relationships that life has with non-living matter. “Biosphere meets Geosphere” per- haps most parsimoniously describes the fundamental con- cept of Geobiology. In 1991, Peter Westbroek, a Dutch paleontologist and influential protagonist of Geobiology defined the field in a book entitled “Life as a Geological Force: Dynamics of the Earth”, thus motivating a new way of thinking in the geosciences.

  • (BQ) Chapter 8: Process costing. We continue our discussion of the details of a product costing system in Chapter 8 by developing a process costing system. As we discussed in Chapter 6, the difference between job order and process costing is the level at which costs are aggregated before they are assigned to the individual units of product. Process costing assumes that all units are homogeneous and follow the same path through the production process.

  • (BQ) Chapter 9: Activity-based costing. Chapters 7 and 8 described product costing systems. In the last 15 years or so, many companies have experimented with and implemented costing systems based on production processes rather than accounting systems. One such system is activity-based costing, or ABC, which aids managers in the decision making process. Chapter 9 describes activity-based costing.

  • The field of industrial electronics covers a plethora of problems that must be solved in industrial practice. Electronic systems control many processes that begin with the control of relatively simple devices like electric motors, through more complicated devices such as robots, to the control of entire fabrication processes. An industrial electronics engineer deals with many physical phenomena as well as the sensors that are used to measure them.

  • Sensor Fundamentals Digital techniques have become increasingly popular in processing sensor outputs in data acquisition, process control, and measurement. Generally, 8-bit microcontrollers (8051-based, for example) have sufficient speed and processing capability for most applications. By including the A/D conversion and the microcontroller programmability on the sensor itself, a “smart sensor” can be implemented with self-contained calibration and linearization features, among others. A smart sensor can then interface directly to an industrial network as shown in Figure 1.2.4.
