Conductive Level Switches

Conductive Level Switches from KOBOLD offer precise and reliable level detection for conductive liquids. They operate by measuring the electrical resistance between a sensing electrode and a ground reference. Because the design has no moving parts, it handles difficult media like low density liquids, high viscosity liquids, or liquids with large quantities of particulates. Conductive level switches are commonly used in industries such as water treatment, chemical processing, and pharmaceuticals, where maintaining the correct liquid level is essential for process efficiency and end-user safety.

KOBOLD's conductive level switches are designed for easy installation and integration into existing systems. They provide real-time data and control capabilities, ensuring efficient process management. Explore our range of conductive level switch products listed below to find the best solution for your specific application needs.
