About the…
About Siemens’ Transducers
This product is intended for use in industrial areas. Operation of this
equipment in a residential area may cause interference to several
frequency based communications.
The Echomax XPS F series of
transducers operates in association with
Siemens ultrasonic level monitoring
products.
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 Siemens
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
(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.
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 Siemens.
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 Siemens 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
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.

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
* the use of a TS-3 temperature sensor provides better temperature tracking in
applications where the temperature can change quickly.
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.

Applications
Standpipes
In many applications, access must be made via a standpipe. In such cases,
Siemens 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.
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.

Volume
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 13.
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.
5. When used in hazardous areas, the XPS 10 F series transducer (shown)
must use a hazardous seal. This seal is not supplied by Siemens. The XPS
15 F Series transducer comes equipped with a stainless steel coupling
suitable for use in hazardous locations.
