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.
