With the rapid development of AI computing centers, high-density computing clusters, energy storage power stations, and industrial refrigeration equipment, power consumption per cabinet keeps rising. Traditional air cooling can no longer meet the high-efficiency heat dissipation requirements of high-power equipment. With advantages of low PUE, high heat dissipation efficiency and stable operation, liquid cooling has become the mainstream upgrade direction in data centers, energy storage, new energy and industrial refrigeration fields.

The safe and stable operation of liquid cooling systems highly relies on accurate and real-time monitoring of pressure and temperature. Abnormal pressure may cause leakage, flow interruption, blockage and cavitation; abnormal temperature will lead to overheating and frequency reduction of equipment, condensation short circuit and thermal runaway. Sensors with high precision, high reliability, zero leakage and easy integration are the "safety nerves" of liquid cooling systems.

Targeting the harsh working conditions of liquid cooling systems, Xi'an Chinastar M&C proudly launches three dedicated sensors: CS-PT300G1 Pressure Transmitter, CS-PT602D Digital Pressure Transmitter and CS-WPT300G Temperature & Pressure Integrated Transmitter. They fully cover the needs of pressure monitoring, digital networking and integrated temperature-pressure acquisition, providing one-stop sensing solutions for liquid cooling systems.
