ABSTRACT:
A lead-lag compensated gas-filled temperature sensor having an output which essentially matches, without error, the temperature of a flowing airstream in a gas turbine engine during both transient and steady state conditions comprises a pair of gas-filled temperature probes disposed in the airstream and filled with a gas which expands in response to temperature changes in the airstream at different rates, a pressure responsive means having opposite sides in closed fluid communication with the sensors for compensated movement in one direction and valve means disposed adjacent the pressure responsive means controlled by movement of the pressure responsive means to vary the hydraulic pressure in a system to be controlled.
