Unilab Ultrasonics Transmitter

Ultrasonic Transmitter

Generates the 40kHz signal which is fed to the transducer cell and also to 4mm sockets on the rear panel of the unit. This latter facility enables a second transducer to be driven simultaneously, providing an in-phase double point source for interference experiments, etc. Facilities are also provided for modulating the output of the transmitter using an audio signal generator or audio amplifier/microphone combination. By this method the transmission of speech or other audio information is possible over a distance in excess of 100m.

Dimensions: case 150 x 95 x 60mm, horn 75 x 100mm mouth diam. x length.

Requires PP9 9V battery (not supplied).
