Product Description: Endress+Hauser Deltabar PMD55 Differential Pressure Transmitter
The Endress+Hauser Deltabar PMD55 Differential Pressure (DP) Transmitter is a precision-engineered instrument designed for critical measurement of differential pressure, level, and flow in demanding industrial applications. Renowned for its exceptional accuracy, durability, and advanced diagnostics, the PMD55 is a cornerstone of process automation in industries such as oil and gas, chemical processing, pharmaceuticals, and water treatment. Combining robust construction with cutting-edge technology, it ensures reliable performance in extreme temperatures, corrosive environments, and hazardous areas.
Technical Excellence The PMD55 operates on a ceramic or metal sensor platform, delivering a measurement range from 0-10 mbar to 0-40 bar with an industry-leading accuracy of ±0.075% of span. This high precision minimizes measurement drift, even under fluctuating process conditions, making it ideal for applications like filtration monitoring, tank level control, and flow calculation via the ΔP method. The device withstands static pressures up to 400 bar (5,800 psi) and process temperatures from -40°C to +120°C (-40°F to +248°F), with optional configurations extending to +150°C (+302°F) for high-heat environments such as steam lines or reactors.
Constructed with 316L stainless steel, Hastelloy® C4, or tantalum wetted parts, the PMD55 resists corrosion from aggressive media, including acids, chlorinated solvents, and abrasive slurries. Its IP66/IP67 and NEMA 4X protection ratings ensure reliable operation in dusty, humid, or washdown environments, while certifications such as ATEX, IECEx, and SIL 2/3 guarantee compliance in explosive atmospheres (Zone 0/1/2).
Smart Functionality and Diagnostics Equipped with Heartbeat Technology, the PMD55 continuously monitors its own health, detecting issues like diaphragm fatigue, sensor drift, or electronics failure. This predictive maintenance feature aligns with NAMUR NE107 standards, providing early warnings to prevent unplanned downtime. The transmitter supports 4-20 mA HART, PROFIBUS PA, and Foundation Fieldbus outputs, enabling seamless integration with PLCs, DCS, and SCADA systems. Wireless configuration and diagnostics are simplified via Bluetooth® connectivity and the Field Xpert app, allowing technicians to adjust settings, run diagnostics, or retrieve data without physical access to the device.
