E+H PMP55 Pressure Sensor Digital Transmitter Chemical Process

The Cerabar PMP55 is an intelligent pressure transmitter from E+H, featuring a fully welded metal diaphragm seal. Designed specifically for extreme conditions of ultra-high temperature, high pressure, and strong corrosion, it excels in pressure and level measurement under harsh environments, while also offering functional safety and hygienic certification.

• High-temperature compatibility: PMP51 up to 130°C, PMP55 up to 400°C, suitable for high-temperature steam, heated reactors, and similar applications.
• Diaphragm sealing technology: Fully welded metal diaphragm with filling fluid isolates sensors from high-temperature or corrosive media, protecting the sensor and extending service life.
• Strong corrosion resistance: Multiple wetted material options (tantalum, Alloy C, etc.) enable use in extreme media such as strong acids, strong alkalis, and high-salinity environments.
• Dual certification for functional safety and hygiene: Globally certified for SIL2, 3-A, EHEDG, explosion protection (Ex ia/ib), and marine classification (DNV).
• Modular design: Display and electronic modules can be replaced individually, reducing maintenance costs and downtime; compatible with PMP51/PMC51 platforms, enabling interchangeable spare parts.

• Process Industry: High-temperature and high-pressure pipelines/containers in chemical, oil & gas, power, and metallurgy industries for pressure, level, volume, or mass measurement by Endress+Hauser.
• Hygienic Industry: Sterile/clean environments in food, and consumer goods, supporting measurements of high-temperature steam and highly viscous media by Endress+Hauser.
• Functional Safety: Complies with SIL2 (IEC 61508/IEC 61511) for safety-related pressure monitoring.
• Special Conditions: Highly corrosive media (e.g., acids and alkalis), high-temperature steam, high-viscosity or particulate-laden media, and applications requiring remote-sealed transmission.

The PMP55 is E+H's flagship pressure transmitter designed specifically for extreme high-temperature, high-pressure, and highly corrosive conditions. Equipped with three core technologies—diaphragm sealing, TempC diaphragm, and multi-material compatibility—it effectively addresses challenges such as high temperature, corrosion, and remote transmission. Widely used in high-end process industries including chemical, oil & gas, the PMP55 is the preferred choice for pressure measurement in demanding operating environments.
