Abstract

The invention relates to an ultrasonic device for transmitting and receiving ultrasonic pulses, comprising at least one transducer (1), which is capable of converting electrical signals into ultrasonic signals and vice versa. An electronic control circuit is included in the device and comprises a transmitting state adapted to excite the transducer, in a transmitting mode, causing it to transmit ultrasonic pulses as well as a receiving stage adapted to process, in a receiving mode, ultrasonic signals received by the transducer and converted into electrical reception pulses. The device further comprises a separating circuit adapted to automatically provide electrical separation of the transmitting and receiving stages in at least the receiving mode of the ultrasonic device. The receiving stage is connected to the transmitting stage via one or more diodes (4) each of which is oriented in such manner that, in the receiving mode, it blocks current in the direction from the transmitting stage towards the receiving state whereas, in the transmitting mode, it conducts current in the direction from the reeiving stage towards the transmitting stage.
