This equipment has been tested and found to comply with the limits for a Class B
Note:
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate, radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving transducer.
• Increase the separation between the equipment and receiver.
• Connect the equipment to an outlet on a different circuit from the one to which the

SITRANS Probe LU is a 2-wire loop-powered, continuous level monitor that uses advanced
ultrasonic techniques. The instrument consists of an electronic component coupled to the
transducer and process connection.
The transducer is available in ETFE (ethylene-tetrafluoroethylene) or PVDF (polyvinylidene
fluoride), allowing SITRANS Probe LU to be used in a wide variety of industries and
applications using corrosive chemicals.
The ultrasonic transducer contains a temperature-sensing element to compensate for
temperature changes in the application.
Communication is via PROFIBUS PA. This device supports acyclic communications from both a
PROFIBUS Class I and Class II master. Signals are processed using Sonic Intelligence® which
has been field-proven in over 500,000 applications worldwide (ultrasonic and radar).
SITRANS Probe LU is available in three versions:
• General Purpose (non-hazardous)
• Intrinsically Safe (with suitable barrier)
• Non-Incendive (FM Class I, Div. 2)
