Differential pressure Deltabar PMD55

Differential pressure transmitter with metal sensor for measurement of pressure differences

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, vapours and gases. Quick Setup with adjustable measuring range allows simple commissioning, reduces costs and saves time. SIL2 according to IEC 61508 / IEC 61511.

Benefits

Easy menu-guided commissioning via local display, 4 to 20mA with HART, PROFIBUS PA, FOUNDATION Fieldbus
Easy process adaptation to impulse line high-pressure/low-pressure change via electric switch on the main electronics
Compact design and modular concept for easy replacement of display or electronics
Process pressure up to SIL2, certified to IEC 61508 and IEC 61511
Global usage thanks to the widest range of approvals for industries and applications

Field of application

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.
