Process controls exist in almost every manufacturing plant.  There are three elements to every process control unit:

            First is sensing, which entails specific equipment that has been designed to calculate temperature, energy, pressure, volume, among other measures, for each designated process.  The second aspect of process control instrumentation is the controls part, or brain.  This usually takes the form of an input or output box.  It transmits information to the instrumentation being used in the sensing activities and commands when to stop or continue each specific function.  The third aspect of process controls is operation, or the control of the manufacturing process. 

            In most factories today, computers control operations.  If any malfunction occurs, the process control unit detects it and a message will flash.  It is a technician’s job to then resolve the problem.

            Sales of process controls in Mexico are heavily influenced by microprocessors and computer-related technology.  As more microprocessor-controlled instruments are introduced into the industry, the demand for computer networks that manage these instruments will grow.  This growth will allow for efficient production processes.

            Improvements in sensor technology have also allowed for more accurate readings and to improve analysis and control of production processes and have led the local industry to a more intensive use of microprocessor-driven instruments and networks.

            The total market for process controls in Mexico is estimated at a little over $1.3 billion (imports plus total production minus exports is the total market and is almost the same figure as total imports). Industrial investment and research and development will enhance future prospects in this sector.  The Mexican market for process control instrumentation should continue to grow in years to come if market conditions remain...
