About Milltronics’ Transducers
The transducer operates by converting electrical
pulses that are provided by the transceiver into
ultrasonic pulses. When transmitted, these
ultrasonic pulses reflect from the material surface
and echo back to the transducer. The echo is
converted back to an electrical signal, and is
interpreted by the Milltronics tranceiver using
our proven Sonic Intelligence™ algorithms.
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
axis of
(perpendicular) from the transducer face in a
transmission,
line referred to as the axis of transmission.
perpendicular
Where power is reduced by half (– 3 dB), a
to transducer
conical boundary defining the sound beam,
face
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.
Hazardous Area Applications
The Echomax XPS F series of transducers can be used in hazardous areas.
For the XPS 10 F series transducer, a hazardous seal must be used to suit
hazardous area classification. This seal is not supplied by Milltronics.
The XPS 15 F comes equipped with a stainless steel coupling suitable for
use in hazardous locations.

Mounting
Recommendations
• 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 (0.3m for XPS 10 F and 0.45m for XPS 15 F). Refer
to the associated transceiver manual for instructions on setting the blanking
value.
• 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 over-tighten 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.

Interconnection
Note:
Installation should only be performed by qualified personnel and in
accordance with local governing regulations.
Recommendations
• When using an XPS 15 F transducer, configure the electronic transceiver for
an XCT-12. These two transducers use the same settings.
• 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.
Note:
In the interconnection examples that follow:
•
an XPS 10 F Series transducer is shown. An XPS 15 F transducer can
also be used, but no hazardous seal is required.
•
assume that the transducer is located in a Hazardous location (Class I,
Div. 1, Group A,B,C,D or Class II, Div. 1, Group E,F,G.) and the
transceiver in a Non-Hazardous (Safe) Location.

Applications
Notes:
• 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.
• An XPS 10 F Series transducer is shown in these examples. An XPS
15 F transducer can also be used, but no hazardous seal is required.
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.
Note:
Refer to transceiver manual for programming requirements.

Standpipes
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 measurement.

Applications
In many applications, access must be made via a standpipe. In such cases,
Milltronics can provide factory bonded flanged transducers or a split flange
kit that will readily mate to the flanged standpipe. Another option is to hang
the transducer from a blind flange.

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 (XPS 15 F) represents a rise:run of about 20:1 (10:1 for the 12° beam
angle of the XPS 10 F). 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 page 19.
3.
Echo has missed improperly levelled transducer.
4.
When performing an empty or full calibration, the tank must contain its
normal vapour and be at its normal temperature.

When used in hazardous areas, the XPS 10 F series transducer (shown)
must use a hazardous seal. This seal is not supplied by Milltronics. The
