Diamond-Hinman radiosonde

[¦dī·mənd ¦hin·mən ′rād·ē·ō‚sänd] (engineering) A variable audio-modulated radiosonde used by United States weather services; the carrier signal from the radiosonde is modulated by audio signals determined by the electrical resistance of the humidity- and temperature-transducing elements and by fixed reference resistors; the modulating signals are transmitted in a fixed sequence at predetermined pressure levels by means of a baroswitch.
