Setting a New Benchmark for Absolute Pressure Measurement! The Endress+Hauser PMP71 Absolute Pressure Transmitter Launch

Accuracy Up to 0.05%, Supports HART/Bluetooth, Providing Ultra-Stable Measurement Solutions for Extreme Industrial Processes

In the field of high-end process industries, the measurement of absolute pressure in critical processes such as vacuum, distillation, and evaporation demands unprecedented levels of accuracy and reliability. To meet this challenge, Xi'an Xinyi Instrument Technology Co., Ltd. formally introduces and promotes the industry-leading Endress+Hauser PMP71 Absolute Pressure Transmitter. This product combines the convenience of flange mounting with laboratory-grade measurement accuracy, specifically designed for industries with extremely stringent measurement requirements such as chemicals, pharmaceuticals, and semiconductors. It aims to provide comprehensive and reliable monitoring from micro-pressure to ultra-high pressure.

1. Laboratory-Grade Measurement Performance:
   The core advantage of the Endress+Hauser PMP71 Pressure Transmitter lies in its exceptional accuracy. Its standard accuracy reaches ±0.05%, with an optional platinum accuracy grade of up to ±0.025%. Furthermore, its measurement range is exceptionally wide, reaching up to 700 bar maximum and capable of measuring minute absolute pressures as low as 0~500 Pa. It can accurately capture the most subtle pressure changes in processes, providing a reliable data foundation for advanced process control and research & development.

2. Future-Oriented Intelligent Diagnostics:
   This transmitter is not just a measurement unit but an intelligent process partner. It natively supports the 4-20mA HART protocol and offers optional Bluetooth functionality for wireless remote commissioning and data access. Its unique "Heartbeat" Technology continuously verifies device health and detects process anomalies, while an intuitive design changes the backlight from green to red during alarms, making field status clear at a glance. This significantly enhances predictive maintenance capabilities and operational safety.

The outstanding performance of the Endress+Hauser Absolute Pressure Transmitter PMP71 is built upon its robust parameters for handling extreme operating conditions:

• Extensive Adaptability and Ruggedness: Both ambient and medium temperature ranges span from -40℃ to +85℃, with an optional diaphragm seal extending the process temperature to 400℃. An IP65 protection rating and stainless steel construction ensure stable operation in damp, dusty, and corrosive environments.

• Flexible Installation and Interfaces: Offers various process connection methods including flange and threaded. A ceramic contact media surface enhances corrosion resistance. Its two-wire design with a 12~36VDC power supply range allows for simple installation and wiring.

• Comprehensive Pressure Type Support: In addition to core absolute pressure measurement, this series is also compatible with gauge and sealed pressure types, offering multi-purpose functionality in one device to meet complex application needs.

Thanks to these top-tier specifications, the PMP71 Pressure Transmitter is indispensable in the following high-demand scenarios:

• Chemicals and Petrochemicals: Distillation column absolute pressure control, reactor vacuum monitoring, high-pressure polymerization processes.

• Pharmaceuticals and Biotechnology: Lyophilizer chamber pressure monitoring, fermenter absolute pressure measurement, cleanroom pressure differential control.

• Semiconductor Manufacturing: High-precision vacuum measurement in process chambers for Chemical Vapor Deposition (CVD), etching, etc.

• Power and Energy: Steam turbine condenser vacuum monitoring.

As a professional supplier of industrial instruments, Xi'an Xinyi Instrument Technology Co., Ltd. has been committed to providing high-quality measurement solutions to global customers since 2017. We commit that the supplied Endress+Hauser products meet original factory standards, backed by a two-year warranty and professional selection and technical service support. Our products are sold to global markets including Northern Europe, the Middle East, and North America.

The introduction of the Endress+Hauser PMP71 Absolute Pressure Transmitter represents the clear direction of process measurement technology evolving towards ultra-high precision, intelligent diagnostics, and wireless connectivity. By providing unquestionable measurement accuracy and deep process insight, it empowers users to achieve a leap from "monitoring" to "prediction" and from "control" to "optimization."

Choosing the PMP71 is not merely selecting a transmitter; it is equipping your core process with an intelligent partner capable of "perception" and "communication." Together, they ensure production safety, optimize efficiency, and confidently meet the challenges of future industrial intelligent upgrades.
