Description
Endress+Hauser PMD55: Precision Pressure Sensing Solutions
Endress+Hauser Deltabar PMD55 is built for plants that need dependable differential pressure data without unnecessary complexity. At TPT24, we position this transmitter for engineers who want a proven, service-friendly instrument for daily process control and safety-relevant measurement loops.
Because it is designed for continuous measurement across liquids, vapors, and gases, Deltabar PMD55 fits a wide range of industrial duties. It supports fast project execution when you need consistent results from commissioning through long-term operation.
Key Features and Benefits of Endress+Hauser Deltabar PMD55
The core benefit of Endress+Hauser PMD55 is confidence in measurement under real plant conditions. Its piezoresistive sensor and welded metallic membrane are selected to support stable readings and durability in demanding applications.
Endress+Hauser PMD55 is also designed to reduce time spent on setup. Quick Setup and an adjustable measuring range help technicians configure the device efficiently, which can reduce commissioning effort in both new builds and upgrades.
Communication and control-system compatibility
For control integration, Endress+Hauser PMD55 supports widely used interfaces. Available options include 4-20 mA HART, PROFIBUS PA, and FOUNDATION Fieldbus, enabling straightforward connection to DCS and PLC environments.
This flexibility helps standardize instrumentation strategies across sites. It also supports consistent diagnostics and parameter handling practices within established maintenance workflows.
Technical Highlights of Endress+Hauser Deltabar PMD55
Endress+Hauser Deltabar PMD55 is specified with a standard reference accuracy of 0.1%, with an optional “Platinum” version reaching 0.075%. For long-term performance planning, it is characterized by stability values of 0.05% of URL per year, 0.13% of URL over 5 years, and 0.23% of URL over 10 years.
The transmitter is engineered to operate across a process temperature range of -40°C to +85°C, with a similarly broad ambient temperature capability. In addition, Endress+Hauser Deltabar PMD55 covers measuring cell pressures from 10 mbar up to 40 bar, and it is designed to withstand an overpressure limit of 160 bar on one side.
Safety and approvals for global projects
For safety-related applications, Endress+Hauser Deltabar PMD55 is stated as SIL2 certified according to IEC 61508 / IEC 61511. This supports use in safety-instrumented functions where documentation and proven device behavior matter.
For hazardous area and international deployment, the device is associated with approvals such as ATEX, FM, CSA, CSA C/US, IEC Ex, INMETRO, NEPSI, and UK Ex. It also references design approvals including NACE MR0175 and EN10204-3.1, supporting selection for challenging service conditions when required.
Typical Applications and Industries for Endress+Hauser Deltabar PMD55
PMD55 is used for differential pressure measurement across filters, pumps, and process equipment to help identify fouling, blockage, or performance losses. This makes it valuable for improving uptime and maintaining consistent production quality.
It is also applied to level, volume, or mass measurement in liquids, supporting inventory visibility and process control. In addition, Endress+Hauser Deltabar PMD55 can be used for flow measurement in gases, vapors, and liquids when paired with appropriate primary elements, enabling both volume and mass flow calculations depending on the installation concept.
Installation and Integration Advantages of Endress+Hauser Deltabar PMD55
PMD55 is designed with a compact form factor that helps when mounting space is limited. Its modular concept supports simpler service actions by enabling replacement of the display or electronics module without unnecessary disruption.
To support adaptability in the field, PMD55 includes an electric switch on the main electronics for changing impulse line high-pressure/low-pressure configurations. This can simplify reconfiguration during plant modifications or when impulse line routing changes.
