Description
The LS-15-600 Series PTFE Single-Level Float Switch is engineered for reliable performance in environments where chemical resistance, purity, and durability are critical. Constructed entirely from high-quality Teflon® (PTFE), this float switch is ideal for use in ultra-pure, corrosive, and chemically aggressive liquids, commonly found in industries such as semiconductor manufacturing, chemical processing, pharmaceuticals, biotechnology, and laboratory applications.
One of the key benefits of PTFE is its non-stick surface, which naturally resists fouling from sticky substances, sludge, and particulate matter. This characteristic significantly reduces maintenance and ensures consistent float movement even in contaminated or viscous fluids. Its inert, chemically resistant nature makes it suitable for handling acids, solvents, and other reactive compounds that would degrade standard plastic or metal float switches over time.
Designed for vertical installation, the LS-15-600 features a compact build with a 1/8″ NPT threaded mounting and a 1.10″ float diameter, making it well-suited for tanks, vessels, and equipment where space is limited. The float activates at a specific gravity of 0.70, allowing for accurate level sensing even in low-density liquids. It can withstand a maximum pressure of 25 PSI at 150°F and operates across a wide temperature range from -40°F to 375°F, ensuring reliable performance in both hot and cold process environments.
This model includes an SPDT reed switch rated at 3 VA, capable of switching up to 100 VAC/DC with a maximum current of 0.25A. It is ideal for use in control panels, alarm systems, and monitoring devices. The unit also comes with 24-inch long, Teflon-insulated 22 AWG lead wires, providing secure, heat- and chemical-resistant connectivity for a wide range of applications.
For added versatility, the float can be inverted to change its switching function from Normally Open (N.O.) to Normally Closed (N.C.), or vice versa. This allows the same unit to be used in different control configurations without requiring additional parts.
Whether you’re working with harsh chemicals or need a highly reliable float switch for sensitive operations, the LS-15-600 Series offers long-lasting performance, chemical stability, and installation flexibility, making it a trusted solution in the most demanding environments.
