ABOUT THE TRANSDUCER
The Echomax XPS F 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 receiv e 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 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.
The XPS F series 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.

DO’S AND DON’TS
Mount the transducer so that it is
value
. Refer to the associated transceiver manual.
On liquid applications, the transducer must be mounted so that the axis of transmission is
perpendicular to the liquid surface.
On solids applications, a Milltronics Easy Aimer should be used to facilitate aiming of
the transducer.
Do not overtighten mounting
Secure installation by connecting a safety chain from the transducer to a structural member.
Consider the optional
