Industrial salinity sensor is a high-precision digital sensor suitable for long-term online monitoring of various complex water quality environments. Its measurement range is 0–300‰ (customizable), with an accuracy of 2%FS and a resolution of up to 0.1‰. SUCH salinity sensor has an IP68 waterproof rating, supports multiple power supply options including DC 5V/12V/24V, and provides 4–20mA and RS485 isolated outputs for easy integration into various industrial control systems. It is suitable for use in industrial wastewater treatment, chemical industries, swimming pools, water plant laboratories, aquaculture, and other scenarios, maintaining stable operation in environments ranging from 0~60℃.
Industrial salinity sensors are suitable for applications requiring long-term monitoring of water salinity, such as industrial wastewater treatment, chemical process control, aquaculture, water treatment facilities, laboratory analysis, and drinking water and circulating water systems.
Industrial salinity sensors are typically based on the principle of conductivity measurement, calculating salinity by detecting the conductivity of water. Because dissolved salts increase the conductivity of water, the sensor can calculate the corresponding salinity value based on the change in conductivity.
To ensure measurement accuracy, it is recommended to clean the electrode surface regularly to prevent dirt, algae, or sediment from affecting the measurement. If the operating environment is complex, the maintenance frequency may be increased appropriately.
