High-Purity Water Requirements in Taiwan’s Semiconductor Industry
In semiconductor manufacturing, ultra-pure water (UPW) and chemical filtration systems are critical to maintaining stable production processes. As advanced semiconductor technologies continue to evolve, semiconductor fabs are demanding even higher standards for water purity and equipment reliability. If filter blockage, abnormal differential pressure, or delayed monitoring occurs within the filtration system, it may affect process stability and increase downtime and maintenance costs. As a result, real-time monitoring of filtration equipment has become an important part of semiconductor facility management.
1. Customer Background
Taiwan Semiconductor Manufacturing Company (TSMC) continues to expand its advanced fabrication facilities while simultaneously investing in large-scale water treatment and utility system projects to meet the high standards required for semiconductor manufacturing processes. Since semiconductor production requires large volumes of ultra-pure water and chemical fluids, filtration equipment and circulation systems within water treatment facilities must operate continuously and reliably.
2. Customer Challenges
Semiconductor water treatment systems operate 24/7, and filter elements can gradually accumulate contaminants over time, resulting in differential pressure changes. Without real-time monitoring, issues such as filter blockage, reduced flow rate, increased energy consumption, and unexpected downtime may occur, while also increasing inspection and maintenance workloads.
3. Customer Requirements
To improve system management efficiency and equipment reliability, the customer required a differential pressure monitoring solution capable of real-time filter monitoring, alarm contact output, corrosion resistance, and stable long-term operation. The goal was to reduce manual inspection workload while improving maintenance efficiency and operational safety.
4. Solution
To meet the customer’s requirements, SJ Gauge provided a “Contact Differential Pressure Gauge” solution for filtration system monitoring. The gauge can simultaneously monitor inlet and outlet pressure to directly display differential pressure changes and quickly identify filter blockage conditions.
When the differential pressure exceeds the preset value, the built-in contact output can immediately trigger alarm signals for easy integration with PLC and control systems.
The product features a large dial design for clear visibility during on-site inspections and utilizes a stainless steel structure to enhance corrosion resistance and long-term durability. It is suitable for semiconductor water treatment systems, UPW systems, chemical filtration systems, and utility engineering applications.

5. Conclusion
SJ Gauge’s contact differential pressure monitoring solution helps TSMC monitor filtration system operating conditions in real time, allowing maintenance personnel to quickly identify filter pressure loss changes and reduce the risk of unexpected downtime.
Through differential pressure monitoring and alarm functions, the solution improves equipment management efficiency while reducing manual inspection workload. Combined with its durable stainless steel construction and high-visibility design, it fully meets the semiconductor industry’s demand for high reliability and stable operation.
