Industrial controllers

The result of this study can be exploited in the practice of the industrial control of long product in conductor material. 

Specialized equipment for industrial measurements and automatic control have been developed (18) (see Process control). In general, the pH of an industrial process need not be controlled with great accuracy. Consequendy, frequent standardization of the cell assembly may be uimecessary. On the other hand, the ambient conditions, eg, temperature and humidity, under which the industrial control measurements are made, may be such that the pH meter must be much more robust than those intended for laboratory use. To avoid costiy downtime for repairs, pH instmments may be constmcted of modular units, permitting rapid removal and replacement of a defective subssembly.

In most industrial control applications, a process has already been almost completely defined and a tailored control system is built around that process. Our application is different. Because we wish to develop a consistent control approach for many, varied processes, flexibility is exceptionally important to us.

Small farmers in the USA find it difficult to use the services of packing houses and distributors, either because they are considered too small to bother with or because such services are owned by their large competitors. The four largest firms in the meat-packing industry control more than 80% of the beef market. There are other concerns over the power of the large corporations. Industry giants get free access to shelf space in supermarkets for popular manufactured items, whereas smaller companies must pay fees for similar access. 

The host of new synthetic organic pesticides presents a variety of problems to the practicing physician because of the lack of basic fundamental information on these chemicals. The American Medical Association has organized a committee on pesticides to consider the following problems of economic poisons and to coordinate information and make it available to physicians and other interested persons or groups safe standards of use, development of prophylactic and antidotal measures, voluntary industry controls, standardization of nomenclature, and professional and public education. 

In the processing industry, controllers play a crucial role in keeping our plants running—virtually everything from simply filling up a storage tank to complex separation processes, and to chemical reactors.
