YEX-S2-EC-S Online Conductivity Sensor Key Advantages

1. High Precision and Temperature Compensation Optimization

Measurement accuracy reaches ±1.5%F.S. (conductivity) and ±0.3℃ (temperature), with a resolution of 1μS/cm. It uses two-point calibration combined with Pt1000 automatic temperature compensation algorithm, maintaining excellent stability within the 0～60℃ operating range, significantly reducing measurement errors caused by temperature fluctuations and meeting the stringent requirements of industrial process control.

2. Strong Anti-Interference and Flexible Integration Capability

Adopts RS485 digital communication (Modbus/RTU protocol) and 4-20mA analog output. The dual output design greatly improves system compatibility. The 5-core shielded twisted pair effectively resists electromagnetic interference in industrial sites, supports long-distance transmission and multi-device networking, and facilitates seamless integration into existing control systems, reducing integration costs and wiring complexity.

3. Industrial-Grade Protection and Corrosion-Resistant Design

IP68 protection rating allows long-term submersion. Wetted materials combine ABS, POM and 316L stainless steel with excellent corrosion resistance. Equipped with M16-5 pin waterproof connector and 5-meter anti-corrosion shielded cable (customizable). The 3/4 NPT thread installation method is suitable for pipe, tank and immersion installation, making installation and maintenance convenient.

4. Low Power Consumption and Standardized Maintenance

Power consumption is only 0.2W@12V, suitable for continuous online operation. It undergoes 72-hour aging and stability testing before leaving the factory. Maintenance is simple: regularly clean the electrode surface with a soft brush and rinse with distilled water, then maintain performance with two-point calibration, significantly reducing user operation and maintenance costs.
