Your benefits
• Choice of three level operating modes
• Volume and mass measurements in any tank shapes by means of a freely programmable characteristic curve
• Choice of diverse level units with automatic unit conversion
• A customised unit can be specified
• Has a wide range of uses, e.g.
– for level measurement in tanks with superimposed pressure
– in the event of foam formation
– in tanks with agitators of screen fittings
– in the event of liquid gases
– for standard level measurement
Communication protocol • 4...20 mA with HART communication protocol
• PROFIBUS PA
– The Endress+Hauser devices meet the requirements as per the FISCO model.
– Due to the low current consumption of 13 mA ± 1 mA
– up to 7 Deltabar S for Ex ia, CSA IS and FM IS applications
– up to 27 Deltabar S for all other applications, e.g. in non-hazardous areas, Ex nA, etc.
can be operated at one bus segment with installation as per FISCO.
Further information on PROFIBUS PA, such as requirements for bus system components, can be found in
the Operating Instructions BA034S "PROFIBUS DP/PA: Guidelines for planning and commissioning" and in
the PNO guideline.
• FOUNDATION Fieldbus
– The Endress+Hauser devices meet the requirements as per the FISCO model.
– Due to the low current consumption of 15 mA ± 1 mA
– up to 6 Deltabar S for Ex ia, CSA IS and FM IS applications
– up to 24 Deltabar S for all other applications, e.g. in non-hazardous areas, Ex nA, etc.
can be operated at one bus segment with installation as per FISCO.
Further information on FOUNDATION Fieldbus, such as requirements for bus system components can be
found in the Operating Instructions BA013S "FOUNDATION Fieldbus Overview".
