A temperature sensor for mounting on a mast of a helicopter has a heat sensor positioned within a central openining in a radially finned heat exchanger. The heat sensor and heat exchanger are spaced rearward from the mast on a tubular sensor support. Long wires helically coiled within the sensor support connect the sensor and terminals on a bracket soldered to the mounting base. The rearward mounting of the heat sensor and the spacing of the heat exchanger and sensor from the mast on the sensor support and the coiling of a long wire within the sensor support between the sensor and terminals on the base and the filling of the sensor support with polyurethane foam resin ensure that the sensor senses air temperature remote from its base and does not sense temperature of the element on which the base is mounted.
