PMD55 Differential pressure Deltabar

Field of application

The Deltabar PMD55 differential pressure transmitter with piezoresistive sensor and welded metallic membrane is typically used in process or environmental applications for continuous measurement of pressure differences in liquids, vapors and gases. Quick Setup with adjustable measuring range allows simple commissioning, reduces costs and saves time. SIL2 according to IEC 61508 / IEC 61511.

For level, volume or mass measurement in liquids, differential pressure monitoring, e.g. of filters and pumps as well as flow measurement (volume or mass flow) in conjunction with primary elements in gases, vapors and liquids.
