STE01 Submersible Liquid Level Transmitter

The STE01 submersible level transmitter features a high-performance diffused silicon piezoresistive pressure sensor, designed to accurately measure liquid level based on hydrostatic pressure proportional to depth. With a measuring range of 0–0.5 to 200 mH2O, it supports multiple output signals including 4–20mA, 0–10V, and Modbus RS485, making it ideal for industrial automation and remote monitoring systems. Its integrated structure with IP68 protection ensures reliable long-term operation in harsh environments ranging from -40°C to +125°C. Constructed with 304/316L stainless steel or titanium alloy, it is compatible with various corrosive media. Widely used in applications such as water wells, wastewater treatment, rivers, seawater, and industrial water systems, the STE01 provides a durable and efficient solution for precise liquid level measurement and control in industries like oil, chemical processing, power plants, and municipal water supply.
