Ultra Fast Thermometer (UFT)
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
