Presicting Temperature Controller Maintenance

摘要

As technology improves, products continue to evolve. For example, the cost of electronic devices has fallen, even as they became smaller in size and offered improved performance. There is no reason to believe that this trend will slow any time soon. Likewise, temperature controllers have experienced these changes; and at the same time, their role in processes has changed dramatically. Temperature controllers now are used not only to control temperature but also to identify process behavior and prevent downtime. The electronic controllers of the 1970s and early 1980s had an analog design. While these instruments improved upon the performance of their predecessors, they were limited to providing a single function — controlling the process's temperature.
