Unilab Ultrasonics Receiver

The transducer is of the same type as used in the transmitter but in this case used as a detector, its output being applied to a d.c. amplifier circuit. A pair of 4mm sockets allow connection to a 1mA meter for quantitative work. A gain control is also provided so that the output from the receiver provides full scale deflection of the meter under maximum signal conditions. If speech or other audio modulation is used the output from the receiver should be connected to an audio amplifier/loudspeaker combination.

Dimensions: 150 x 95 x 60mm
