System and method for estimating operating temperature of turbo machinery

摘要

A method (700) for estimating an operating temperature of component in turbo machinery includes providing (701) a body detachably affixed to component, operating (703) machinery, stopping (705) operation of machinery, and removing (707) the body. The method (700) includes obtaining (709) a concentration profile by determining (711) the final concentration of at least one species in a first material and in a second material, and determining a transient concentration of at least one species between the first material and the second material. The method (700) includes determining an operating temperature by correlating concentration profile to corresponding operating temperature for system.
