1. A sensor, comprising:
an airfoil body defining a sensor axis and an insulating cavity, the airfoil body extending between a leading edge and a trailing edge of the airfoil body;
a heater element extending axially within the airfoil body, the heater element positioned between the leading edge and the trailing edge of the airfoil body;
a temperature probe extending axially within the airfoil body and positioned between the heater element and the trailing edge of the airfoil body, wherein the temperature probe is separated from the heater element by the insulating cavity to limit thermal communication between the temperature probe and the heater element;
a pressure inlet disposed at the leading edge; and
an expansion chamber fluidly connected to the pressure inlet via an inlet segment;
wherein the heater element is disposed axially between the pressure inlet and the expansion chamber.
