PMD75
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).
