2. Key Selling Points

1. High-Precision Conductivity Measurement for Process Reliability: The AC3218 is a high-performance conductivity sensor utilizing 2-electrode or 4-electrode measurement technology (depending on configuration), enabling precise and stable measurement of liquid conductivity. It is suitable for various applications such as pure water, industrial water, and cleaning solution concentration monitoring, ensuring product quality and process consistency.
2. Robust Hygienic Design: Specifically designed for high-demand industries like food & beverage, pharmaceuticals, and biotechnology, it features a high-quality stainless steel housing (AISI 316L/1.4435) and hygienic process connections (e.g., DIN 11851, SMS, ISO 2852 clamps). With an IP68/IP69K protection rating, it withstands high-pressure, high-temperature water, and steam cleaning during CIP (Clean-in-Place) and SIP (Sterilize-in-Place) processes.
3. Integrated Temperature Compensation: Equipped with an integrated Pt1000 temperature sensor, it simultaneously monitors the medium's temperature and automatically applies temperature compensation (typically to 25°C), eliminating the influence of temperature fluctuations on conductivity readings and providing more accurate and comparable results.
4. Dual Output: Analog + IO-Link: Supports a standard 4-20mA analog output for easy integration with conventional PLCs or control systems, and includes an IO-Link interface for digital communication. This allows transmission of multiple parameters—conductivity, temperature, device status, and diagnostics—and enables remote parameterization and predictive maintenance.
