The P48W Gauge Pressure Switch from UE Precision Sensors is engineered to deliver accurate and repeatable pressure switching in high-purity gas applications. Designed for monitoring pressure above atmospheric conditions (gauge pressure), this switch is commonly used for alarm, control, and shutdown functions in sensitive process environments.
Built with a fully welded stainless steel construction and factory-set calibration, the P48W ensures consistent performance without the need for field adjustments. Its robust internal design supports long-term reliability, making it a trusted solution for semiconductor manufacturing and other contamination-sensitive systems.
Why the P48W stands out:
- Designed specifically for high-purity gas applications
- Provides precise gauge pressure measurement (above atmosphere)
- Built for long service life with minimal maintenance
- Factory-set for tamper-resistant, consistent performance
These capabilities make the P48W ideal for applications where pressure accuracy and system protection are essential.
