Ưu điểm kỹ thuật quan trọng
-
High-Pressure Durability: The piezoresistive metallic sensor is designed for heavy-duty applications, capable of measuring ranges from vacuum up to 400 bar. This makes it the preferred choice for high-pressure hydraulic systems, steam applications, and gas distribution.
-
Precise Temperature Compensation: The PMP51 provides highly accurate process values even when subjected to rapid changes in process temperature. This thermal stability is critical for outdoor installations or processes with fluctuating fluid temperatures.
-
Safety and Integrity: The device is certified to SIL2 according to IEC 61508 and IEC 61511, making it a reliable component for safety instrumented systems (SIS). It also offers a “Platinum” accuracy grade of ±0.075% for high-precision requirements.
-
Hygienic Excellence: For food and pharmaceutical applications, the PMP51 offers small, flush-mounted process connections. This design eliminates dead legs and ensures process safety during sterilization and cleaning cycles.
-
Modular Data Handling: The modular concept allows for the easy replacement of the local display or electronics without removing the transmitter from the process. This “plug-and-play” capability reduces downtime and lowers total cost of ownership.
-
Simplified Commissioning: Featuring menu-guided operation via the local display or digital protocols (HART, PROFIBUS PA, FOUNDATION Fieldbus), the transmitter can be set up quickly with adjustable measuring ranges to match specific process needs.
