Data Acquisition with PID Control CX2000 (INTERRUMPIDO)

The Japan Steel Works, LTD., Muroran Plant uses the Control and Measurement Station CX2000, UP series program controllers, and UT series digital indicating controllers for operation of its heat treating furnaces. The Japan Steel Works (JSW), LTD., Muroran Plant is located in an industrial area looking over Muroran port in Muroran City, Hokkaido.

The making of ceramics is one of the oldest forms of heat-treating known to man. Clay, silica or some type of high purity alumina is shaped, dried, milled and then baked at extremely high temperatures. This high baking process changes the clay material to stone or glass. Depending on the properties that are desired from the end product will determine the material used and the method of firing the work.

MEGTEC Systems, a major manufacturer of Regenerative Thermal Oxidizers in DePere, Wisconsin is now specifying DAQSTATION for use with their equipment. These oxidizers, commonly known as RTOs, are found in Paint Finishing Operations, Chemical, Petro-chemical and Ethanol Production, Ink Coating and Odor Abatement, and many other applications on a global basis.

The basic principles of canning have not changed dramatically since Nicholas Appert and Peter Durand developed the process in the 18th century. Heat sufficient to destroy microorganisms is applied to foods packed into sealed, or "airtight" containers. The canned foods are then heated under steam pressure at temperatures of 240-250°F (116-121°C).

Thermal oxidizers, also known as fume incinerators or afterburners, are widely used to control air emissions. Many processes, such as paint baking, drying of printing inks and curing of certain polymers, evolve vapors of flammable, toxic solvents. In the baking or curing oven, these solvent vapors pose an explosion or fire hazard, so they are diluted well below their lower limit of flammability by adding large amounts of dilution air.

The rapid evolution of information technology (IT) has made possible the transmission of a wide range of information in a short period of time, resulting in the transformation of society in aspects such as logistics and business styles. During this transformation, quick assessment of the circumstances and prompt actions were also required in the production lines, making real-time collection of field information indispensable.
