Deltabar S Differential Pressure
The Deltabar S differential pressure transmitter is used for the following
measuring tasks:
• Flow measurement (volume or mass flow) in conjunction with primary
elements in gases, vapors and liquids
• Level, volume or mass measurement in liquids
• Differential pressure monitoring, e.g. of filters and pumps
• International usage thanks to a wide range of approvals
Benefits include:
• Very good reproducibility and long-term stability
• High reference accuracy: up to ±0.075%, as PLATINUM
version: ±0.05%
• Turn down 100:1, higher on request
• Used for flow and differential pressure monitoring up to SIL 3, certified to
IEC 61508 by TÜV SÜD
• HistoROM®/M-DAT memory module
• Function-monitored from the measuring cell to the electronics
• Continuous modularity for differential pressure, hydrostatic and pressure
(Deltabar S, Deltapilot S, Cerabar S), e.g.
– Replaceable display
– Universal electronics for pressure and differential pressure
• Extensive diagnostic functions
• Choice of four flow modes of operation: volume flow, norm volume flow
(European norm conditions), standard volume flow (American standard
conditions) and mass flow
