Description

Application

The Deltabar PMD55 differential pressure transmitter, equipped with a piezoresistive sensor and a welded metallic membrane, is ideal for continuous pressure difference measurement in liquids, vapors, and gases within various process and environmental applications. Its Quick Setup feature with an adjustable measuring range ensures easy commissioning, reducing time and cost. It complies with SIL2 standards as per IEC 61508 / IEC 61511.

It is suitable for level, volume, or mass measurement in liquids, differential pressure monitoring (e.g., for filters and pumps), and flow measurement (both volume and mass flow) when used with primary elements in gases, vapors, and liquids.

Process connections: Threads
Process temperature: -40 to 85°C (-40 to 185°F)
Measuring ranges: 0.5 mbar to 40 bar (0.0072 to 600 psi)
Accuracy: ±0.1%, with an optional "Platinum" accuracy of ±0.075%
Certifications: International explosion protection certificates and SIL compliance

Benefits

Simple Commissioning: User-friendly menu-guided setup via local display, supporting 4 to 20mA with HART, PROFIBUS PA, and FOUNDATION Fieldbus.
Easy Process Adaptation: Quick adjustment of impulse lines for high- or low-pressure changes using an electric switch on the main electronics.
Modular and Compact Design: Compact structure with a modular design for easy replacement of the display or electronics components.
Certified for Process Safety: Supports process pressures up to SIL2, certified according to IEC 61508 and IEC 61511.

Global Applicability: Approved for a wide range of industries and applications worldwide.
