Deltabar PMD75
Differential pressure transmitter with
meta
l sensor for measurement of pressure differences
The Deltabar PMD75 differential pressure transmitter with with piezoresistive sensor and welded
meta
llic membrane is used in all industries for continuous measurement in liquids, vapors and gases. The 3-key operation enables simple and reliable commissioning and operation. The integrated HistoROM data module allows easy management of process and device parameters. Designed according to IEC 61508 for use in SIL2/3 safety applications.
For level, volume or mass measurement in liquids, differential pressure monitoring as well as flow measurement (volume or mass flow) in conjunction with primary elements in gases, vapors and liquids.
