Abstract: The invention relates to a temperature measuring device for measurement of the external temperature of the ambient air in a vehicle, wherein the temperature measuring device is disposed in a flow path of an air flow and the air flow can be generated from ambient air of the vehicle both through speed-dependent wind resistance of the vehicle and/or wind and also through a compressor unit disposed in the flow path.

Abstract: The temperature sensor is particularly suitable for a fever thermometer which has outer dimensions of, for example, 4 mm diameter and 40 mm length. To provide the requisite stiffness, the outer sleeve is made of stainless steel or specialty steel of thin walls, for example less than 0.1 mm wall thickness, closed at one end, and the temperature sensor is positioned essentially exposed, and naked at the end of a positioning body formed of two half-sections of low-density foam material, in which a longitudinal groove is formed, through which the connecting wires of the temperature sensor extend. The longitudinal groove can be filled by a springy element, for example unitary with one of the half-sleeves, or a separate positioning rod. The connecting ends of the sensor conductors can be connected to a coaxial cable, and the end portion can have a handle plastic-molded thereabout.
