STE02 Smart Submersible Level Transmitter (IP68 High Accuracy)

The STE02 Level Transmitter utilizes high-performance diffused silicon or titanium alloy sensing elements to accurately measure hydrostatic pressure proportional to liquid depth and convert it into a standard 4–20mA output signal. This enables precise and reliable liquid level monitoring. Featuring an IP68 protection rating and submersible split-type design, the transmitter offers compact structure, excellent durability, and stable performance even in high-temperature and harsh environments. An integrated LCD display provides real-time level readings for improved on-site usability. The STE02 is widely used in industries such as oil & gas, chemical processing, power plants, municipal water supply, wastewater treatment, and hydrological monitoring. It is suitable for applications involving tanks, wells, sewage systems, rivers, seawater, and more. With high accuracy (up to ±0.1% F.S), outstanding long-term stability, and strong anti-interference capability, the STE02 is an ideal solution for industrial liquid level measurement and control.
