ABOUT THE TRANSDUCER
The Echomax XPS / XCT series of transducers
operates in association with Milltronics ultrasonic
level monitoring products.
transducer
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.
transducer face
– 3 db
boundary
The effective acoustical energy is emitted from
axis of
the transducer face and radiated outward,
transmission,
decreasing in amplitude at a rate inversely
perpendicular to
proportional to the square of the distance.
transducer face
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 / XCT 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.
GENERAL GUIDELINES

ambient temperatures in the range of - 40°C to 95°C and the XCT series is only certified for
use in ambient temperatures in the range of -40°C to 145°C. Neither should be used outside
of their respective temperature ranges.
Installation shall be carried out in accordance with the applicable code of practice, and by
suitably trained personnel.
These devices should only be supplied from a circuit containing a suitably-rated fuse that has
a breaking capacity of 4000A. This fuse is included in Siemens Milltronics’ transceivers.

MOUNTING
DO’S AND DON’TS
Special handling precautions must be taken to protect the face of the transducer from any
damage.
Mount the transducer so that it is above the maximum material level by at least the blanking
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. Hand tightening of the mounting hardware is sufficient.
Secure installation by connecting a safety chain from the transducer to a structural member.
Consider the optional temperature sensor when mounting the transducer.

DO’S AND DON’TS
Installation shall only be performed by qualified personnel and
in accordance with local governing regulations.
Do not route cable openly.
For optimum isolation against electrical noise, run cable separately in a grounded
metal conduit.
Seal all thread connections to prevent ingress of moisture.
Do not run cable near high voltage or current runs, contactors and SCR control drives.

APPLICATIONS
The transducer is to be used only in the manner outlined in this instruction manual.
Normally, the transducer requires no cleaning or maintenance. However, if performance
changes are observed, immediately shut down the level measurement system and perform a
thorough inspection, especially on the transducer.

LIQUID APPLICATIONS - SUBMERGENCE
In applications where flooding is possible the transducer▼ can be fitted with a submergence
shield. The shield acts as a bell to create an air pocket in front of the transducer face. The
associated transceiver▼ interprets this as a flooding condition, and reacts accordingly.
Refer to transceiver manual for programming requirements.

LIQUID APPLICATIONS - STANDPIPES
In many applications access must be made via a standpipe. In such cases, Milltronics can
provide factory bonded flanged transducers or split flange kit that will readily mate to the
flanged standpipe. Another option is to hang the transducer from a blind flange.
The standpipe length should be as short and the diameter as large as possible. As a rule of
thumb, the -3 dB cone of the sound beam should not intersect the standpipe wall in
applications opening into a vessel or larger area. Otherwise, additional blanking will be
required to compensate for the interference zone created by the opening.
Note: When using a stilling well, make sure there is no build-up, welds, couplings, or other
debris on the inside of the well wall. This can affect reliability of level measurement.

1. Beam should not detect bin bottom. If this occurs use range extension parameters
(on transceivers where available) to omit false echoes. A 6° beam angle represents a
rise : run of about 20 : 1 (10 : 1 for 12°). In most tanks, the transducer should be
centered as much as possible (without interference from inlet) for optimum reading range.
2. Sound beam must be perpendicular to liquid surface.
If standpipe is used, refer to Liquid / Applications - Standpipes.
3. Echo has missed improperly leveled transducer.
4. When performing an empty or full calibration, the tank must contain its normal vapour and
be at its normal temperature.
