4 20ma Conductivity Sensor

The 4–20mA Conductivity Sensor is a reliable and high-precision device designed for continuous measurement of electrical conductivity in water. This advanced conductivity sensor provides accurate and stable readings, helping monitor the concentration of dissolved ions in various water treatment and industrial process applications. Adopts high-quality electrodes and advanced signal processing technology to ensure fast response, high measurement accuracy, and long-term operational stability. With a standard the conductivity sensor can easily integrate with PLC, DCS, and other industrial control systems for real-time monitoring and automated process control.

Equipped with automatic temperature compensation (ATC), the 4–20mA Conductivity Sensor maintains reliable measurement accuracy even when the water temperature changes. The sensor is designed with a durable and corrosion-resistant housing, allowing stable performance in demanding industrial environments. is widely used in drinking water treatment plants, wastewater treatment facilities, industrial circulating cooling water systems, boiler water monitoring, aquaculture operations, and environmental water quality monitoring projects. Continuous conductivity monitoring helps optimize water treatment efficiency and maintain stable process conditions.
