Interface Switches

Interface switches in industrial process control detect boundaries between two different substances within tanks or vessels, including liquids, gases, and solids. Essential for maintaining product integrity and safety, these switches operate by identifying physical property changes—such as density, conductivity, or thermal characteristics—between adjacent media. Reliable interface switches prevent contamination, overflow, and system malfunction. They integrate seamlessly into control systems, enabling precise automation, monitoring, and system optimization. Interface switches are vital across diverse industries such as chemical processing, petrochemicals, pharmaceuticals, and wastewater treatment, providing robust performance in challenging operational environments.
