Abstract:
A material test device for testing material to be employed in an environment separate from said test device comprising:a transducer assembly having at least one transducer component for converting electrical energy to acoustic energy and for converting acoustic energy to electrical energy;a sample holder operatively connected with said transducer assembly;a sample chamber in said sample holder for receiving and holding a sample of material that is to be tested;a reflective surface included in said sample holder and spaced from said transducer assembly whereby acoustic energy waves transmitted from said transducer assembly travel through said sample chamber and are reflected from said reflective surface back through said sample chamber to said transducer assembly; andelectrical circuitry operatively connected with said transducer assembly for supplying electrical power to said transducer assembly for producing acoustic energy waves and for receiving and analyzing electrical signals produced by said transducer assembly in response to reflected, acoustic energy waves.
