Thermal Level Switches

Thermal Level Switches

Thermal dispersion level switches are precision instruments designed to detect and monitor the presence or absence of liquids and slurries in industrial vessels, tanks, and pipelines. They function by measuring the heat transfer difference between a heated sensor and the surrounding media. When the level reaches the sensing element, a measurable temperature shift occurs, triggering a relay or electronic output. Thermal dispersion technology offers reliable, repeatable detection without moving parts, reducing maintenance requirements and enhancing operational safety.

The robustness and simplicity of thermal dispersion level switches make them exceptionally useful in challenging industrial environments. They operate reliably in a broad range of temperature and pressure conditions, tolerate harsh process media, and remain unaffected by changes in density, viscosity, or dielectric properties of fluids. This versatility makes them highly suitable for conditions where traditional mechanical switches or floats may fail due to fouling, turbulence, or vibration.

Typical applications span multiple industries, including oil and gas, petrochemical processing, wastewater management, power generation, and food and beverage production. In oil and gas sectors, these switches manage critical overflow and leak prevention functions. In chemical plants, they monitor aggressive substances, ensuring safety and process efficiency. Wastewater facilities employ them to prevent overflow, while in food production, they help maintain hygiene and product consistency.

Thermal dispersion level switches provide an essential control solution, combining ruggedness, accuracy, and ease of integration into automated control systems, significantly enhancing process reliability.
