YIGUCS offers a similar configuration to the Memiuyelay model, focusing on compatibility with major commercial ice machines. The featured temperature sensor provides real-time readings to optimize ice-making cycles. High-quality materials offer wear and oxidation resistance with stable performance and precise signal transmission. This makes it suitable for demanding facilities that require dependable, temperature-aware float switching in ice machines and related equipment.
uxcell Stainless Steel Float Switch for Water Pump Tank
uxcell’s stainless steel float switch is suited for water pumps, tanks, pools, and ponds. It features a 116 mm length version with M10 screw fittings, DC 100 V switching capability, and 10 W maximum switching power. The design supports flexible installation at the top or bottom of a tank, accommodating detection of rising or falling liquid levels. The robust stainless steel construction ensures reliability in a range of liquids and temperatures, providing a practical option for high-temperature environments.
uxcell Stainless Steel Float Switch for Water Pump Tank – M11
This variant from uxcell extends the stainless steel float switch family with an M11 screw size, offering compatibility with installations requiring a taller float assembly. It shares the same DC switching capability (up to 110 V) and 10 W max switching power, with a 26×27 mm float ball size and a 300 mm wire length. The longer length allows flexible mounting options for tank and pump setups, making it appropriate for larger vessels or systems where space constraints necessitate longer reach.
Buying Guide: Key Considerations For High Temperature Float Switches
Selecting a high-temperature float switch involves balancing materials, electrical ratings, and environmental compatibility. Here are critical factors to consider:
- Material and Corrosion Resistance: Stainless steel variants (304/316L) provide excellent durability in hot, wet, or chemically aggressive environments. Verify corrosion resistance relative to the liquid being monitored.
- Temperature Tolerance: For ice machines or hot water tanks, confirm the switch’s ability to function reliably near the process temperature. Built-in temperature sensors can add precision for temperature-dependent control.
- Electrical Ratings: Check switching voltage and current to ensure compatibility with your pump, valve, or control circuit. Low-voltage and high-voltage options may be required based on the system.
- Installation and Fit: Consider threaded sizes (M10, M11, 3/4″), float ball dimensions, and overall length. Ensure the mounting method matches your tank or drain configuration.
- Water Density and Pressure: Some models specify operating pressures or ranges; ensure the device can handle the liquid density and head pressure in your application.
- Integrated Features: Temperature sensors, piggyback plugs for troubleshooting, and normally-closed vs normally-open contacts affect control logic and maintenance.
- Maintenance and Cleaning: Removable caps or easy-to-clean designs simplify service in food service or condensate drainage applications.
In practice, choose a model with a robust stainless steel body for environments with elevated temperatures and pressures, ensure the electrical ratings align with your control system, and prefer units with temperature sensing or higher IP ratings if moisture exposure is a concern. For ice makers, a 2-in-1 switch with a built-in temperature sensor provides the most precise control over freezing cycles. For pool and pump applications, look for standard mounting options (M10/M11) and a balance between long wire runs and compact form).
