Thermal Interface Switches

Thermal interface switches identify media boundaries based on thermal conductivity differences between fluids or solids. These switches feature heated sensor elements immersed directly within process media. When interface transitions occur, changes in heat dissipation rate signal a media shift, activating an electrical output for control and alarm actions. Highly accurate, repeatable, and unaffected by pressure, viscosity, or buildup, thermal switches excel in demanding industrial environments. They're ideal for petroleum refining, chemical plants, water treatment, and food processing, providing effective monitoring of liquid-liquid, liquid-gas, and solid-fluid interfaces under harsh process conditions.
