About the Transducer
The Echomax XLS / XLT series of
transducers operates in
association with Milltronics
ultrasonic level monitoring
products.
The transducer converts the
electrical energy of the transmit
pulse from the transceiver into
acoustical energy. It then
converts the acoustical energy
of the echo back into electrical
energy for the transceiver
receive period.
The effective acoustical
energy is emitted from the
transducer face and radiated
outward, decreasing in
amplitude at a rate inversely
proportional to the square of
the distance. 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 def ining 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 pow er from the
transducer into air and vice versa.

About the Transducer
The XLS / XLT 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 wires.
