General Guidelines - Siemens XPS Operating Instructions Manual

Introduction
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/XCT series of transducers operate with
Siemens Milltronics ultrasonic level monitoring products.
The transducer converts the electrical 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 radiating
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 XPS/XCT transducers have an integrated temperature sensor that reports the air
temperature at the transducer to the controller.

General Guidelines

Materials of construction are chosen based on their chemical
WARNING:
compatibility (or inertness) for general purposes. For exposure to specific
environments, check with chemical compatibility charts before installing.
XPS/XCT Series – Certificate SIRA 99ATEX5153X
This equipment may be used in hazardous areas associated with all gases with
temperature classes T1, T2, T3 and T4 for the XPS series (XPS-10, XPS-15, XPS-30, and
XPS-40) and T1, T2, and T3 for the XCT series (XCT-8 and XCT-12). The XPS series is only
certified for use in ambient temperatures in the range of - 40 °C to 95 °C and the XCT
series is only certified for use in ambient temperatures in the range of -40 °C to 145 °C.
Neither should be used outside of their respective temperature ranges.
Installation shall be carried out in accordance with the applicable code of practice, and
by suitably trained personnel.
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 controllers.
Repair of this equipment shall be carried out in accordance with the applicable code of
practice.
