Abstract
A quench cooling effectiveness apparatus for continuous monitoring of a heat treat quench system and method of operation is provided. The apparatus preferably includes first and second heat conductive sheaths having temperature sensors installed therein. The heat conductive sheaths are thermally insulated from each other with a heat resistive sheath. A microprocessor is preferably connected to said sensors, applies a known current to one sensor, and calculates a cooling effectiveness of the heat treat quench system from the temperature of the two sensors and the known applied current.
