ABSTRACT:
An apparatus for measuring the temperature of a medium such as air or the like by the use of a change in the propagation speed of an ultrasonic sound wave depending on the temperature change of the medium. An acoustic transmitter transmits a carrier as an ultrasonic sound wave continuously through the medium to a receiver by exciting an ultrasonic wave vibrator with a series of pulses which constitute the carrier. The received ultrasonic wave when amplified exhibits a series of pulses having a constant signal level irrespective of a change in the amplification factor of the amplifier in the receiver.
