Standex Detect - Reed Liquid Level Sensors
Reed liquid level sensors use magnetic floats and reed switch technology to detect fluid levels. As the float moves with the liquid, it activates reed switches housed within a stem, providing a reliable on/off signal or triggering multiple level points. These sensors are highly energy-efficient, drawing no power until activated, making them ideal for battery-powered or low-energy applications.
They are available in vertical or horizontal mount configurations and can be customized for various fluid types, temperatures, and pressures. With options for stainless steel or plastic housings, reed sensors offer a simple, cost-effective solution for fluid level monitoring in automotive, industrial, HVAC, and appliance systems.
