ABSTRACT:
A device for detecting failure of an ultrasonic apparatus having an ultrasonic pulse generator, an ultrasonic transmitter and an ultrasonic receiver utilizes a damped oscillation signal which is produced at the junction point between the ultrasonic pulse generator and the ultrasonic transmitter when the ultrasonic transmitter or the ultrasonic receiver is excited by applying thereto an ultrasonic pulse generated by the ultrasonic pulse generator. A level discriminator compares the damped oscillation signal with a reference level and determines whether the damped oscillation signal has a sufficient magnitude and duration indicating that the ultrasonic transmitter or the ultrasonic receiver is in a normal operating condition.
