Submersible Hydrostatic Liquid Level Sensor with 4–20mA / RS485 Output (IP68)
A robust, submersible level sensor designed for accurate liquid level measurement in tanks, wells, and water systems. Featuring a stainless steel probe, IP68 protection, and 4–20mA or RS485 output, this unit provides reliable, long-term monitoring for industrial and environmental applications.
This submersible hydrostatic liquid level sensor is designed for continuous level measurement in water and compatible liquids across a wide range of industrial and environmental applications. Using a high-stability diffusion silicon sensing element, the transmitter converts hydrostatic pressure into a precise level signal for reliable monitoring.
The sensor is fully sealed within a stainless steel housing, with an integrated protective diaphragm that allows direct contact with the liquid while protecting the sensing element from damage and contamination. A waterproof, breathable cable with an internal vent tube ensures accurate atmospheric pressure compensation, improving measurement stability over time.
With support for both 4–20mA analog output and RS485 digital communication, the sensor can be easily integrated into PLCs, RTUs, data loggers, and monitoring systems. Its IP68-rated construction allows for permanent submersion, making it suitable for use in tanks, reservoirs, boreholes, and open water environments.
Designed for reliability in harsh conditions, this level transmitter offers a practical and cost-effective solution for water level monitoring in municipal, industrial, agricultural, and environmental systems.
