Ultimate Precision, Ceramic Pioneer: The E+H Cerabar PMP71 Flange-Mount Absolute/Gauge Pressure Transmitter

In the process industry, the precise measurement of pressure and level often faces extreme challenges such as high temperature, high pressure, and strong corrosion. An instrument capable of maintaining performance under such demanding conditions is key to ensuring process safety and efficiency. Xi'an Xinyi Instrument Technology Co., Ltd. presents the E+H (Endress+Hauser) Cerabar PMP71 Absolute/Gauge Pressure Transmitter. This flagship product, with its Platinum accuracy up to 0.025%, wide range coverage up to 700 bar, and innovative corrosion-resistant ceramic diaphragm, and optional remote seal system for temperatures up to 400°C, sets a new benchmark for performance and reliability in critical pressure and level measurement applications across industries such as oil, chemicals, power generation, and pharmaceuticals.

1. Core Technology: Corrosion-resistant ceramic sensors, impervious to harsh conditions
   The core advantage of the PMP71 lies in its use of the Contite measuring element—a capacitive sensor made from high-purity ceramics. Compared to traditional metal diaphragms, ceramic sensors exhibit exceptional resistance to overload, corrosion, and wear. Their surfaces can directly contact corrosive media such as strong acids and alkalis without the need for a separating diaphragm, fundamentally eliminating the risk of filling liquid leakage and ensuring the highest integrity and long-term stability of measurements.
2. Unparalleled measurement performance
   Thanks to advanced sensor and signal processing technologies, the PMP71 delivers impressive performance metrics. Its standard accuracy reaches 0.05%, with an optional platinum-grade precision of 0.025%, meeting the most demanding measurement and control requirements. The range spans from 500Pa micro-pressure to 4MPa, and when paired with a diaphragm sealing system, it can extend up to 700bar, enabling flexible adaptation to various working conditions from vacuum to ultra-high pressure.
3. Intelligent Diagnosis and Convenient Operation
   The transmitter supports advanced Heartbeat Technology, enabling online self-calibration and process anomaly monitoring. It verifies instrument health without interrupting the process flow, significantly enhancing plant reliability and maintenance efficiency. Additionally, an optional Bluetooth interface allows engineers to perform remote debugging, parameter configuration, and fault diagnostics via smartphones or tablets, revolutionizing traditional on-site operations. A clear backlight display changes from green to red during alarms, ensuring instant visibility.
4. Abundant options for remote transmission sealing systems
   • Compact diaphragm seal: Suitable for high-temperature applications or situations requiring flush connections.
   • Temperature isolator diaphragm seal: Protects sensors from extremely high temperatures (up to 400°C).
   • Diaphragm sealing with capillary tubes: enables long-distance separation between sensors and process measurement points.

Core parameters, defining flagship performance:

• Petroleum and Chemical Industry: Monitoring of reactor pressure, distillation column pressure, tank liquid level, and pipeline pressure. Ceramic diaphragms can withstand highly corrosive media.
• Power and Energy: Measurement of boiler drum pressure, feedwater system pressure, and steam turbine steam pressure, with optional diaphragm sealing for high-temperature conditions.
• Pharmaceutical and Biotechnology: Monitoring of fermentation tank pressure, sterilizer cabinet pressure, and pharmaceutical water system pressure to meet hygiene and high-precision requirements.
• Metallurgy and Papermaking: Measurement of blast furnace gas pressure, pulp level, and hydraulic system pressure.
• Food and Beverage: Monitoring of tank liquid levels, pipeline pressure, and sterilization equipment pressure.
