In wastewater plants, pumps can be damaged if they run without fluid or if tanks overflow. The EMD-SL-LL-230 relay helps manage both risks by monitoring the lowest and highest liquid points with precision. When water drops too low, the system automatically stops pumps, avoiding dry-run damage. If levels rise too high, the relay signals shutdown to prevent spillage. Its flexible sensitivity settings ensure accurate switching even with fluctuating fluid conductivity, while the short-circuit and open-circuit monitoring protects against faulty wiring. This makes it highly reliable for large treatment basins that must handle diverse liquid conditions while maintaining safety and uptime.
Chemical plants often store fluids with different conductivity, from acids to solvents, which makes reliable level detection challenging. The EMD-SL-LL-230 monitoring relay adapts with adjustable sensitivity, ensuring dependable operation across a wide range of substances. Its dual monitoring capability prevents overfilling of hazardous chemicals while also ensuring that tanks do not run dangerously low. Built-in error detection safeguards against wiring issues, allowing operators to respond before a fault leads to a spill or equipment failure. By providing fast, accurate switching and the ability to work with conductive probes, this relay helps manufacturers maintain consistent product quality and strict safety standards.
Backup generators depend on a steady fuel supply to ensure continuous power in emergencies. The EMD-SL-LL-230 is well-suited for monitoring diesel or oil storage tanks, preventing both shortages and overfills. Its two independent changeover contacts allow one channel to feed control logic for the generator while the other triggers alarms or notifications for operators. Because it tolerates varying cable lengths and different fuel conductivities, it performs reliably even when tanks are located at a distance from control systems. By protecting fuel supply integrity, it minimizes downtime risk, ensures readiness, and extends the life of critical backup systems in remote facilities.
In food and beverage processing, maintaining precise ingredient levels in mixing tanks is essential for consistent recipes. The EMD-SL-LL-230 ensures that ingredients such as syrups, cream, or liquid additives stay within safe ranges. Its monitoring function stops processes if tanks approach empty levels, preventing air entry, and halts filling if the tank is close to overflowing. The integrated test/reset button allows quick verification of sensor performance without halting production. Its compact design fits easily into crowded control cabinets, and its compliance with safety standards supports hygienic plant environments. By delivering stable fluid control, it helps producers guarantee quality and reduce waste.
