Renke RS-EC-N01-3-10-EX Integrated Conductivity Sensor (RS485 Modbus-RTU) K=10, 5m Cable

This sensor has a cell constant (K) of 10, which indicates its electrode geometry is optimized for measuring higher conductivity solutions, typically found in industrial wastewater, seawater, or concentrated process streams. A K=10 cell provides a wider measurement range and better signal stability in these applications compared to standard K=1.0 cells used for pure water.

The sensor uses a standard RS485 interface with the Modbus-RTU protocol. Connect the A/B data lines to your RS485 converter or PLC. You will need to configure your master device (like a PLC or PC software) with the sensor's Modbus address and baud rate (typically 9600 or 19200 bps) to read the holding registers containing the conductivity, TDS, salinity, and temperature values.

Yes, the IP68-rated plastic housing provides full waterproof protection for submersion, making it suitable for seawater monitoring. However, for long-term deployment in highly corrosive or biofouling conditions, periodic maintenance and cleaning of the electrode surface is recommended to ensure measurement accuracy and sensor longevity.

The standard included cable is 5 meters. For RS485 communication, you can typically extend the distance up to 1200 meters (at 9600 baud) by using properly shielded, twisted-pair cable and ensuring proper termination. For very long runs, consider using repeaters or signal conditioners to maintain data integrity.
