Endress + Hauser Flow Transmitter 91WA1-11DB0CACA5BA

Differential pressure transmitter with metal sensor for measurement of pressure differences

The Deltabar PMD75 differential pressure transmitter with with piezoresistive sensor and welded metallic 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.

Benefits

Best accuracy, reproducibility and long-term stability

Highest safety due to gas tight feedthrough with capabilities up to SIL2/3, certified to IEC 61508

Easy menu-guided commissioning via local display, 4 to 20mA with HART, PROFIBUS PA, FOUNDATION Fieldbus

HistoROM data management concept for fast and easy commissioning, maintenance and diagnostics

Cost savings with modular concept for easy replacement of sensor, display or electronics

Overload-resistant up to 420bar / 42MPa / 6300psi, function-monitored

Seamless and independent system integration (HART/PA/FF)
