Core Features Submersible Design for Deep Liquid Level Sensing: Functions as a rugged submersible pressure sensor switch engineered to monitor liquid levels in deep tanks, wells, and water bodies, with a pressure range equivalent to 0–60m H₂O (0–588 kPa). This design uses hydrostatic pressure to calculate liquid depth, eliminating the need for floating mechanisms and ensuring reliable operation in turbid or debris-laden fluids. Dual Output for Level Control: Combines a 4–20mA analog output for continuous level data with two configurable SPDT switches, enabling both real-time level monitoring and discrete control actions (e.g., pump activation/deactivation, high/low level alarms). The analog signal provides ±0.25% full-scale accuracy, critical for precise water management in reservoirs or industrial tanks. Waterproof Construction: Encased in a stainless steel 316 housing with a hermetically sealed cable entry, achieving IP68 rating (IEC 60529) for continuous submersion up to 100m. The sensor’s PTFE cable jacket resists abrasion and chemical degradation, ensuring longevity in harsh aquatic environments. Broad Liquid Compatibility: The titanium diaphragm and 316 stainless steel wetted parts ensure compatibility with freshwater, seawater, wastewater, and mild chemicals, making it suitable for municipal water systems, marine applications, and industrial wastewater treatment. Stable Performance in Temperature Variations: Equipped with temperature compensation technology, maintaining accuracy across -10°C to +70°C. This stability is critical for outdoor applications where ambient and liquid temperatures fluctuate significantly. Flexible Integration: The 4–20mA analog output (2-wire, loop-powered) integrates with PLCs, SCADA systems, and telemetry devices (e.g., Siemens S7-1200, Allen-Bradley Micro850). Switch contacts are rated for AC 250V (2A resistive) and DC 30V (1A resistive), supporting direct control of submersible pumps or valve systems. Easy Deployment: Designed with a stainless steel mounting bracket for secure installation on tank walls or well casings. The 10m (standard) or extended PTFE cable allows flexible positioning, while the compact sensor head (45mm diameter × 80mm length) minimizes flow interference in pipes or tanks. Typical Applications The ALCO Switch PSC-S6S is engineered for deep-water level monitoring in submersible environments, with core use cases including: Municipal Water Reservoirs: Installed in water storage tanks or reservoirs to monitor levels, triggering pumps to refill when low or preventing overflow during heavy rainfall. Groundwater Wells: Used in water wells for agricultural irrigation or drinking water supply, providing data on water table levels and controlling extraction pumps to prevent over-pumping. Marine Applications: Deployed in harbors, docks, or ship ballast tanks to monitor water levels, ensuring safe loading/unloading and preventing instability. Industrial Wastewater Tanks: Integrated into wastewater treatment facilities to monitor sludge or effluent levels, controlling transfer pumps to maintain processing efficiency. Flood Monitoring Systems: Used in rivers, canals, or flood-prone areas to detect rising water levels, triggering early warning alarms to protect infrastructure and communities.
