描述
The Deltabar PMD55B represents the new generation of processing optimization—a highly resilient smart differential pressure transmitter engineered for accurate level, volume, or mass monitoring in gas and liquid applications. Fitted with a high-grade metal membrane, it bridges classic field durability with modern wireless control to streamline day-to-day asset management.
Designed to eliminate complex field configurations, the PMD55B features integrated Bluetooth® connectivity and intuitive onboard software wizards. Field technicians can now safely perform error-free SIL commissioning, system checks, and guided proof-testing directly from a mobile device without breaking the process loop or exposing personnel to hazardous environments.
Key Features & Benefits
