The invention discloses a signal transmitting/receiving method and device of a high temperature elastic modulus tester, wherein the method and device adopt the impulse exciting method. The method comprises the following steps: a non-solid contact mode for transmitting acoustic signals is adopted with the gas in the hearth as the medium; when a high-temperature sample in the hearth generates an acoustic signal, the signal is transmitted remotely to a sonic sensor in a cooling environment by utilizing the air in the dense ceramic tube of a transmission device as the medium; and the sonic sensor inputs the received signal in a computer to analyze and process and obtain the high temperature elastic modulus of the material. The device of the invention mainly comprises a transmission medium (2), the ceramic tube (3), the sonic sensor (6) and a cooling system (4). The method of the invention adopts the non-solid contact signal transmitting/receiving mode and overcomes the defect caused by the ...
