Leak Detection Sensor for Liquids

Discover liquid leaks before they cause harmful environmental or structural damage with Daitron's commercial leak detection sensors. Our liquid leak detection sensors reveal leaks from all liquids, including water, harsh chemicals, and other fluids. These reliable sensors do not require moving or mechanical components. Instead, they use the scattering of infrared light via photo-refraction to detect the presence of liquid regardless of the liquid's viscosity, reflectivity, or color.

Note: These components are not intended for use with flammable liquids.

Liquid Chemical & Water Leak Detection Sensors from Daitron

Our commercial leak detection sensors offer a range of advanced features to ensure precise and reliable performance. These sensors operate on the principle of infrared photo-refraction, utilizing light refraction to accurately detect liquids, regardless of viscosity, reflectivity, or color. They feature a robust design with no moving parts, providing NPN or PNP transistor digital output signals for easy integration.

Designed with safety and reliability, they feature watertight IP67 construction and hold UL (File #E202019) and CE certifications, ensuring compliance with industry standards. Our liquid detection sensors are available with Polypropylene (PP) construction and a high-purity Teflon PFA construction for harsh chemical environments.
