Differential Pressure Switch D48W Series

The D48W series differential pressure switches feature 2 ports. Port 1 is suitable for high purity gases or liquids: port 2 is suitable for dry air or inert gases. Products are used to detect variations in a fixed difference between two pressures. Common applications include load-lock chambers, gas delivery systems and mini environments.
