Deltabar S PMD 70/75, FMD 76/77/78
Technical Information
Differential pressure with ceramic and polysilicon sensors for flow,
level and differential measurement
High accuracy with excellent long-term stability
HART
®
, Foundation Fieldbus or PROFIBUS-PA protocols
Applications
Deltabar S pressure transmitters are suitable for:
• Flow measurement (volumetric or mass flow) in
conjunction with primary elements in gas, steam
and liquid applications.
• Level, volume or mass measurement in liquids.
• Differential pressure monitoring, e.g. across filters or
pumps.
• Corrosive or abrasive applications using unique
ceramic sensor technology (PMD 70). For example,
DP measurement across a filter with abrasive
product.
• High temperatures up to 662°F (350°C) with
remote diaphragm seals (FMD 78).
Your benefits
Top of the line technical specifications:
• High long-term stability (0.05% of URL/year)
• High accuracy: up to ±0.075% span (< 15 : 1
turndown), with optional Platinum version (±0.05%
span)
• Turn down 100 : 1 standard, higher on request
Designed with safety in mind to keep your plant,
equipment and personnel safe:
• SIL-2 certificate optional
• Function-monitoring of the measuring cell by the
electronics provides alert upon sensor failure
• Secondary seals standard in every transmitter
• Built-in diagnostic software functionality (e.g.,
user-defined max/min operating window)
• Optional FM and CSA certificates, plus
combination certificates
Modular design for easy repair:
• Replaceable display
• Universal electronics for pressure and
differential pressure
Easy to setup with menu-driven interface, quick setup
menu for standard application modes:
• Pressure
• Level
• Flow
HistoROM/M-DAT memory module enables:
• Quick duplication of measuring points
• Process monitoring via periodic recording of
pressure and temperature values
• Monitoring of events and configuration changes
• Analysis and graphical evaluation of data by ToF tool
software
Flexible commissioning via multiple modes:
• On-board push buttons (external, or inside housing)
• HART
®
handheld operation
• ToF tool (PC software, free of charge with each
transmitter) plus HART modem
• PROFIBUS-PA or Foundation Fieldbus configuration
