Prototype UFT thermometer for in-cloud

measurements onboard DLR DO-228 aircraft.

Characteristics: • measurement principle: resistance thermometer, shielded by aerodynamical rod from impact of cloud droplets;• sensing element: platinum coated tungsten wire, diameter 2.5 micrometers;• time response: of order of 10-4s, depending of the true-air speed;• temperature resolution: better than 0.05K at 70m/s;• data recording: 10Ksamples/second, measurement at every 1cm at 100m/s
