A glass manufacturer tests viscosity on their glass products in R&D labs. The tests are performed at temperatures over 2000*F and require a precision profile controller for ramp rates and dwells. The resistance of the heating system changes at various temperatures, so a phase angle SCR with current limit was used to accurately control the power. The control system was prewired, fused and tested, mounted on a 19″ rack panel, ready for installation.
