Abstract
A gas turbine engine includes a compressor section and a turbine section. A heat exchanger is operable to cool a fluid utilized by a component of the gas turbine engine. The heat exchanger has an inlet and an outlet for the accessory fluid. A strain gauge is associated with the fluid inlet and operable to produce a signal indicative of a temperature of the fluid at the fluid inlet and a strain gauge is associated with the fluid outlet and operable to produce a signal indicative of a temperature of the fluid at the fluid outlet. A controller determines a temperature differential across the heat exchanger by utilizing the signal from the strain gauge at the fluid inlet and the signal from the strain gauge at the fluid outlet. A method and a heat exchanger are also disclosed.
