SITRANS Probe LU (PROFIBUS PA)
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)
WARNING: Changes or modifications not expressly approved by the
manufacturer could void the user’s authority to operate the equipment.
Note:
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.
