The Industrial Stainless Steel Submersible Pressure Level Sensor is designed for accurate liquid level measurement in water, oil, sewage, reservoirs, tanks, and industrial process applications.
Using a high-performance pressure sensing chip with advanced temperature compensation, it converts hydrostatic pressure into a standard 4–20mA output signal for reliable monitoring. The IP68-rated stainless steel housing provides excellent corrosion resistance and long-term durability in harsh environments.
With a measuring range of 0–5 meters, high accuracy, and a 5-meter cable, this sensor is suitable for water treatment, groundwater monitoring, irrigation systems, refineries, and industrial automation requiring stable and precise level sensing.
