Pressure transmitters for Coolant Distribution Units In Data Centers

As high-performance computing and AI workloads continue to grow, data centers are rapidly adopting liquid cooling technologies to manage increasing heat densities. At the center of many liquid cooling systems is the Coolant Distribution Unit (CDU)—a critical component responsible for transferring cooling capacity, circulating coolant, and maintaining stable operating conditions.

Pressure transmitters are a vital part of Coolant Distribution Units in modern data centers. By providing accurate and reliable pressure monitoring, these sensors enable stable coolant circulation, efficient pump control, and early detection of system issues.

The Role of Pressure Measurement in CDUs

A CDU connects the facility's liquid coolant loop with the IT equipment cooling loop, typically through a plate heat exchanger and a set of circulation pumps. Within this system, pressure transmitters monitor several critical points to ensure stable coolant distribution.

Key functions of pressure monitoring include:

• Maintaining stable coolant delivery to server racks

 • Supporting variable-speed pump control

 • Detecting blockages in filters or cold plates

 • Monitoring pressure drops across heat exchangers

 • Preventing pump cavitation and system faults

Without accurate pressure feedback, CDU systems cannot maintain optimal cooling performance or protect sensitive IT hardware.

Key Requirements for Pressure Transmitters in CDU Applications

Data center cooling environments require pressure transmitters with a combination of accuracy, reliability, and compact design.

The M20 industrial-grade pressure transmitter is specifically designed for Coolant Distribution Units In Data Centers.

It employs a highly stable sensor and advanced signal conditioning technology to accurately measure the pressure of gases, liquids, and other media. It achieves high-precision measurement across the wide -40℃~125℃ temperature range and supports multiple output methods, including 4-20mA, 1-5V, and RS485. The output signal is stable and reliable with strong anti-interference capabilities. The product is compact, manufactured using fully automated welding, ensuring excellent sealing and a long service life. It can be widely used in data center cooling systems.

As liquid cooling continues to grow in importance for high-performance computing and AI infrastructure, the demand for high-quality pressure transmitters in CDU applications will continue to expand. Micro Sensor will continue to provide reliable pressure transmitters for the general industry.
