Introduction
The Echomax XLT series of transducers operate with
Siemens Milltronics ultrasonic level monitoring
products.
The transducer converts the electrical energy of the
transmit pulse from the controller into acoustical
energy. It then converts the acoustical energy of the
echo back into electrical energy for the controller.
The transducer face emits acoustical energy that
radiates outward, decreasing in amplitude at a rate
inversely proportional to the square of the distance.
Maximum power radiates perpendicularly from the
transducer face on the axis of transmission. Where
power is reduced by half (– 3 dB), a conical boundary
centered around the axis of transmission defines the
sound beam, the diameter of which is the beam
angle.
The XLT transducers have an integrated temperature
sensor that reports the air temperature at the
transducer to the controller.
General Guidelines
• The equipment may be used in Category 2 (Zone 1), or Category 3 (Zone 2) gas zones and all
hazardous dust zones with all conductive and non-conductive dusts.
• The XLT-30 and XLT-60 series transducers all carry a maximum surface temperature of 200ºC
(i.e. Temperature Class T3). These units are certified for use in an ambient range of –40 ºC to
+150 ºC. Do not use units outside the temperature range.
• 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.
• Repair of this equipment shall be carried out in accordance with the applicable code of
practice/Installation Instructions.
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
.
WARNING: Materials of construction are chosen based on their chemical
compatibility (or inertness) for general purposes. For exposure to specific environments,
check with chemical compatibility charts before installing.

• The certification of the XLT range of transducers relies upon the use of following materials
in the construction:
Aggressive Substances: acidic liquids or gases that may attack metals or solvents that may
affect polymeric materials.
Suitable Precautions: regular checks as part of routine inspections or establishing from
the material’s data sheet that it is resistant to specific chemicals.
For manual override, use the disconnect switch provided in the building installation of the
associated controller.

Enclosure: Aluminum
Encapsulant: Durapot 861-F3 / 864
WARNING: If the equipment is likely to come into contact with aggressive
substances, then it is the responsibility of the user to take suitable precautions
that prevent it from being adversely affected, thus ensuring that the type of
protection is not compromised.
WARNING:This product is designated as a Pressure Accessory per Directive
(7/23/EC and is not intended for use as a safety device.

Mounting
• Mount the transducer so that it is above the maximum material level by at least the
blanking value. Refer to the associated controller manual.
• On liquid applications, the transducer must be mounted so that the axis of transmission is
perpendicular to the liquid surface.
• On solids applications, use a Siemens Milltronics Easy Aimer to aim the transducer.
• Secure installation by connecting a safety chain from the transducer to a structural
member.
• Consider the optional temperature sensor when mounting the transducer.
Solids Applications
Note: Installation shall only be performed by qualified personnel and in accordance with
local governing regulations.
Caution: Wear proper ear protection in the vicinity of the operating transducer.
The XLT 60 transducers could emit hazardous sound pressure. They shall be installed
in such a manner that the sound pressure will be reduced to a non-hazardous level.
WARNING: Easy Aimer configurations are not suitable for pressure applications.
