In Watlow catalogs, brochures and web pages there is a category of controllers listed as “Limits and Alarms”. It is not always clear to everyone when to use these controllers or which type of controller to use. This document is an attempt to clear up some of these issues.

Occasionally questions come up with regard to calibration of Watlow controllers. This paper will attempt to address some of the more common questions on this subject. Many people want to jump in right away and begin performing a calibration procedure before verification. Before you would attempt to calibrate a Watlow controller, verify that the controller is in need of calibration. If you verify that readings of the controller first, you may not have to go through the more involved process of changing the calibration settings.

To comply with the Clean Air Act, a coal-fired power plant needed to heat flue gas to 455°C (850°F). Watlow engineered a customized design that would meet the customer's needs.
