Endress Hauser PMD75 Differential Pressure Transmitter

Core Performance & Industrial Application

The Endress+Hauser Deltabar PMD75 is a differential pressure transmitter with welded metallic piezoresistive sensor for liquids, vapors and gases.

It supports DP flow measurement with primary elements, tank level/volume/mass measurement and filter or pump differential monitoring.

It delivers ±0.05% standard accuracy (±0.035% Platinum option) with overload resistance up to 420 bar.

It provides 4-20mA HART, PROFIBUS PA or FOUNDATION Fieldbus output with HistoROM data module for parameter backup.

It is designed per IEC 61508 for SIL 2/3 safety loops and carries ATEX / IECEx hazardous-area approvals.

It is widely used as spare replacement in chemical, oil & gas and power process measurement.
