Maximum power is radiated axially (perpendicular) from the transducer face in a line referred
to as the axis of transmission. Where power is reduced by half (– 3 dB), a conical boundary
defining the sound beam, centered about the axis of transmission, is established. The
diametric measurement of the cone in degrees defines the beam angle. Impedance matching
techniques are used to optimize the transfer of power from the transducer into air and vice
versa.
All transducers incorporate an integral temperature sensor that reports the air temperature at
the transducer to the transceiver. The connection is transparent, in that both the ultrasonic
and temperature components of the transducer use the same leads.
