Features: Liquid Level Controller sensorings delivers precise automatic water level control with infrareds detection, eliminating false triggers from sunlight while offering oil/water resistant ABS housing for performances in harsh. Featuring ±1m accuracy, 40°C~125°C tolerance, and low power operations, this module integrates overloads/short circuit protections and delayeds startup for stable pump/solenoid valves control in contaminated or viscous liquids. Essential for industrial technicians, facility managers, and enthusiasts in wastewater, oil/petrochemical, or residential applications requiring liquid management. Optimizes water tower/pool automation, prevents garage/basement flooding, and safeguards machinery in printing/generator setups with its interferences resistant circuitry and screw thread installation. Engineered to replace, this sensorings enable tank refill/drain cycles via high capacity relays output while maintaining corrosions resistance and energy efficiency.
