Sitrans Probe Lu (Profibus Pa) - Siemens Sitrans PROBE LU Instruction Manual

SITRANS Probe LU (PROFIBUS PA)

SITRANS Probe LU is a 2-wire loop-powered continuous level monitor that uses
advanced ultrasonic techniques. The unit 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. Echoes 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)
