For enhanced flexibility and integration into sophisticated control systems, the PMD55 offers a range of communication protocols, including 4 to 20mA with HART, PROFIBUS PA, and FOUNDATION Fieldbus. These options ensure seamless communication with distributed control systems (DCS) and programmable logic controllers (PLCs), further contributing to a streamlined and efficient startup phase.

Adaptable Design: Modular, Compact, Efficient

The Endress+Hauser PMD55 features an exceptionally adaptable and modular design, tailored for maximum efficiency and ease of maintenance. Its compact form factor allows for installation in confined spaces, a critical consideration in many modern industrial plants where space is at a premium. The true genius of its design lies in its modular concept, which facilitates the quick and straightforward replacement of key components such as the display or the entire electronics module. This modularity minimizes downtime by allowing for rapid on-site servicing and reducing the need for complete unit replacement. Furthermore, the PMD55 incorporates an electric switch on the main electronics, enabling easy process adaptation to changes in impulse line high-pressure/low-pressure configurations, thus enhancing its flexibility and operational convenience in dynamic industrial environments.

Global Readiness: Widest Approvals, Unmatched Usability

The Deltabar PMD55 is truly designed for global deployment, offering unparalleled usability across diverse industries and applications worldwide. This broad applicability is underpinned by an extensive array of international approvals and certificates, including ATEX, FM, CSA, CSA C/US, IEC Ex, INMETRO, NEPSI, and UK Ex for explosion protection. These certifications ensure that the PMD55 meets stringent safety and performance standards in hazardous areas across different regulatory landscapes. Furthermore, the device holds design approvals like NACE MR0175 and EN10204-3.1, affirming its suitability for demanding process conditions. This comprehensive suite of approvals simplifies procurement and deployment for multinational corporations, guaranteeing compliance and reliable operation regardless of geographical location, thereby solidifying its status as a globally preferred differential pressure solution.

Exceptional Stability, Unwavering Accuracy Assured

The Endress+Hauser PMD55 is celebrated for its exceptional long-term stability and remarkable accuracy, which are critical for maintaining precise process control over extended periods. With a standard reference accuracy of 0.1%, and an optional “Platinum” version achieving an impressive 0.075%, the PMD55 delivers highly reliable measurements. More importantly, its long-term stability is outstanding: 0.05% of URL per year, 0.13% of URL over 5 years, and 0.23% of URL over a decade. This superior stability minimizes measurement drift, significantly extending recalibration intervals and reducing maintenance costs. Such unwavering accuracy and stability ensure that the PMD55 consistently provides trustworthy data, empowering operators to optimize processes, improve product quality, and enhance operational efficiency with complete confidence.

Reliable Performance: Robust Design Elements

The PMD55’s reliable performance stems from a combination of robust design elements and high-quality materials. It is built to withstand challenging industrial conditions with a wide process temperature range of -40°C to +85°C (-40°F to +185°F) and an equally broad ambient temperature range. The measuring cell is capable of handling pressures from 10 mbar up to 40 bar (0.15 to 580 psi), with a maximum overpressure limit of 160 bar (2300 psi) on one side, ensuring durability against unexpected pressure surges. Key components like the process membrane are crafted from durable materials such as 316L and AlloyC, while gaskets are available in Viton, PTFE, EPDM, and NBR, ensuring chemical compatibility. The housing, made from die-cast aluminum, provides excellent protection, contributing to the instrument’s long operational life and consistent performance.
