Product Description
The Endress+Hauser Cerabar PMP50 is a high-performance, versatile industrial pressure transmitter, engineered to deliver precise and reliable pressure measurement for a wide range of industrial process applications. As a flagship product in E+H’s Cerabar series, the PMP50 combines exceptional measurement accuracy, robust construction, and intelligent functionality, making it a trusted choice for process control in oil & gas, chemical, water treatment, power generation, and general industrial sectors. Designed to withstand harsh process conditions—including extreme temperatures, vibration, and corrosive media—this transmitter ensures long-term stability, reduces operational costs, and supports seamless integration into modern control systems.
1. Product Overview & Core Design
The E+H PMP50 is a compact, heavy-duty pressure transmitter designed for gauge, absolute, or differential pressure measurement (configurable based on application needs). Its core design focuses on durability, accuracy, and ease of integration, making it suitable for both standard and demanding industrial environments. Unlike hygienic-specific models, the PMP50 features a robust metal sensor and rugged housing, optimized for industrial process conditions where reliability and resistance to harsh factors are paramount.
Constructed with high-quality materials, the PMP50’s sensor utilizes a precision metal diaphragm (standard 316L stainless steel, optional Hastelloy or tantalum for corrosive media) to ensure accurate pressure detection and long-term resistance to wear and corrosion. The transmitter’s housing is made of die-cast aluminum or stainless steel (optional), with a protection rating of IP67/IP69K, ensuring resistance to dust, water, and high-pressure wash-downs—ideal for outdoor or harsh indoor industrial settings. Its compact, lightweight design allows for easy installation in tight spaces, while its modular construction simplifies maintenance and configuration.
2. Technical Specifications & Performance Parameters
The PMP50 is renowned for its exceptional measurement accuracy and stability, even in dynamic process conditions. Below are its key technical specifications, designed to meet the diverse needs of industrial applications:
- Measurement Range: Gauge pressure: -1...0 bar to 0...1000 bar; Absolute pressure: 0...0.1 bar to 0...1000 bar (depending on model configuration)
- Accuracy: Up to ±0.055% of full scale (FS), ensuring precise and consistent measurement results; optional high-accuracy version (±0.04% FS) available for critical applications
- Output Signals: Standard: 4–20 mA HART (version 7); Optional: IO-Link (IEC 61131-9), pulse output for flow calculation, or digital communication protocols
- Temperature Range: Process temperature: -40°C to +150°C (standard); Optional cooling element for high-temperature applications (up to +250°C); Ambient temperature: -40°C to +85°C
- Pressure Rating: Maximum working pressure: Up to 1000 bar; Burst pressure: 1.5 × maximum working pressure (ensuring safety in high-pressure environments)
- Certifications: CE, ATEX, IECEx, UL, CSA, IEC 61508 (SIL 2/3 certified for functional safety), ensuring compliance with global industrial standards
- Process Connections: Standard: Threaded (G, NPT, BSP), flange (ANSI, DIN); Optional: Diaphragm seal for viscous, corrosive, or crystallizing media
- Power Supply: 12–30 V DC (for 4–20 mA HART); 20–30 V DC (for IO-Link); Low power consumption for energy efficiency
- Response Time: ≤ 10 ms (fast response option: ≤ 1 ms) for real-time pressure monitoring in dynamic processes
- Long-Term Stability: ≤ 0.1% FS per year, reducing the need for frequent calibration and maintenance
