“Continuous galvanizing lines coat steel strip in zinc to make it corrosion resistant by passingthrough a molten zinc pot under tightly controlled temperature conditions. The strip is heated before contacting the zinc, then cooled before further processing. Galvannealed steel also adds a second process, where the strip is heated after zinc coating, causing iron to diffuse into the zinc forming a harder more scratch resistant corrosion resistant iron zinc alloy coating more
suitable for forming and spot welding operations.

Accurate strip temperature must be maintained to produce high-quality products, and in this controlled and varied environment, production engineers and technicians have two broad choices for feedback: thermocouples, which measure conditions via contact temperature measurement and heat conduction, and non-contact sensors, which measure temperature indirectly through radiated heat energy, primarily in the form of infrared radiation.”
