Endress+Hauser Deltabar PMD50

Differential pressure transmitter

Deltabar PMD50 is a metal-diaphragm differential pressure transmitter designed to measure differential pressure, level, or flow of liquids and gases. It is optimized for standard applications and features an intuitive setup interface.

The device supports both simple compressor and manifold connections, as well as protection and certifications for hazardous environments.
