Stainless Steel Float Switch — Water Level Controller (45, 65, 75, 100, 150, 200 mm) Key benefits Reliable level detection: Mechanical float design gives consistent rising or falling water level activation without reliance on electronic sensing, reducing false triggers from electrical interference. Durable in demanding environments: Stainless steel construction resists corrosion and wear for long service life in industrial or residential settings. Easy to install and maintain: Lightweight, vertically mounted unit can be fitted at the or bottom of a tank with no complex circuitry required, simplifying installation and troubleshooting. Flexible sizing and compatibility: Multiple length options (45, 65, 75, 100, 150, 200 mm) let you match sensor depth to your tank or plumbing layout; the silvercolored sensor integrates cleanly with common piping and tank systems. What it does and why you need it Acts as a simple, robust water level controller to protect pumps, prevent overflow, and automate filling or drainage tasks. Provides a stable, mechanical contact signal based solely on buoyancy, so it performs reliably where electronic sensors may be affected by noise, conductivity, or chemical conditions. Works with a variety of tank types and plumbing systems, making it suitable for both residential water tanks and industrial liquid handling. Important features Material: stainless steel body for corrosion resistance and longterm durability. Operation: mechanical float/buoyancy mechanism that triggers on liquid height changes for stable signal transmission. Mounting: vertical installation; can be mounted at the or bottom of tanks for flexible placement. Length options: available in 45 mm, 65 mm, 75 mm, 100 mm, 150 mm, and 200 mm to match different liquid depths and installation needs. Compatibility: intended for integration with industrial or residential plumbing and control systems. Performance and reliability Stable mechanical switching avoids dependency on electronic components, improving reliability in noisy electrical environments or where water conductivity varies. Simple design minimizes maintenance and reduces potential failure points compared with complex circuitbased level sensors. Typical applications Residential water tanks: automatic pump control to prevent dryrun and to stop filling at a set level. Water treatment and drainage systems: level monitoring and control in treatment tanks, sumps, and drainage pits. Industrial electrical control: reliable level switch input for PLCs or relay logic where a durable, nonelectronic signal source is needed. Installation note Select the sensor length that matches your liquid depth. Mount vertically at the chosen or bottom position; the mechanical float will actuate as liquid level rises or falls to provide a reliable control signal. This stainless steel float switch offers a straightforward, durable solution for accurate water level control in a wide range of residential and industrial applications.
