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 provid ed. Identical dimensions to the transmitter. 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. Requires 9V PP9 battery (not supplied). Show more
