Introduction
The Echomax XRS-5 series of transducers operate with
Siemens 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 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 XRS-5 series 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 all hazardous zones with all gases with temperature classes T1,
T2, T3, T4, T5, and T6. The equipment is only certified for use in ambient temperatures in the
range of -20 °C to 65 °C and should not be used outside this range.
• Installation shall be carried out in accordance with the applicable code of practice by
suitably trained personnel.
• The apparatus shall only be supplied from a circuit containing a suitably-rated fuse having
a breaking capacity of 4000A. This fuse is included in Milltronics transceivers.
• Repair of this equipment shall be carried out in accordance with the applicable code of
practice.
• The certification of this equipment relies on the following materials used in its
construction:
• Manual override can be accomplished by using the disconnect switch provided in the
building installation of the associated controller.
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.

Mounting
• Mount the transducer so that it is above the maximum material level bymorethan the
blanking value for accurate results. Refer to the associated transceiver manual for
information on setting the blanking value.
• The transducer must be mounted so that the axis of transmission is perpendicular to the
liquid’s surface.
•Do not over tighten mounting. Hand tightening of the mounting hardware is sufficient.
• Consider the optional temperature sensor when mounting the transducer.
Suspended Conduit Bracket
Flexible conduit transducer should not be
subjected to wind, vibration or jarring.
Submersible Plywood
Submersible transducer, used in
applications where flooding is possible.
Plywood mounting provides excellent isolation,
but must be rigid enough to avoid flexing if
subjected to loading.

Interconnection
Recommended installation rules:
• Do not route cable openly; instead, run cable separately in a grounded metal conduit to
protect it from ambient electrical noise.
• Seal all thread connections to prevent the ingress of moisture.
• Do not run cable near high voltage or current runs, contactors or SCR control drives.
In all of the following examples the terminal blocks on the transceiver are described in the
controller manual.
Blind Flange Face Flange
Note: Tighten the flange bolts evenly in order to ensure a good seal between the mating
flanges.
Caution: Over-tightening can cause performance degradation.
Note: Installation shall only be performed by qualified personnel and in accordance with
local governing regulations.

Direct Connection
Connect the transducer directly to the Milltronics transceiver via the two conductor shielded
cable.
Coaxial Connection
Connect the transducer to the Siemens Milltronics transceiver via a junction box and RG–62 A/
U coaxial cable. This setup is effective for combined runs up to 365 m (1200 ft).
2-Wire Extension
(for EnviroRanger ERS 500, MultiRanger 100/200, and HydroRanger 200 only)
Note: When connecting to an EnviroRanger ERS 500, a MultiRanger 100/200, or a
HydroRanger 200, the white, black, and shield wires are all connected separately. DO NOT
tie the white and shield wires together.
Note: When connecting to an EnviroRanger ERS 500, a MultiRanger 100/200, and
HydroRanger 200, DO NOT use coaxial cable. See diagram below for proper procedure.
