Overview

TracWater TW-4737A online conductivity (salinity) sensor adopts advanced four-electrode technology and features an RS485 digital communication interface that supports the MODBUS protocol. Compared to traditional two-electrode sensors, it provides superior accuracy, a wider measurement range, and enhanced stability. The sensor includes an integrated temperature sensor and employs automatic temperature compensation technology to ensure precise measurements across varying temperature conditions.

Features

  • Equipped with an RS-485 communication interface and supporting the standard MODBUS protocol. 

  • Simultaneously outputs parameters for conductivity, salinity, TDS, and temperature, providing comprehensive monitoring capabilities. 

  • Features a corrosion-resistant housing with an IP68 waterproof rating, allowing for long-term underwater operation in demanding environments. 

  • Includes an integrated temperature sensor with automatic temperature compensation functionality to maintain measurement accuracy across different temperatures. 

  • Includes built-in calibration parameters, accurately calibrated prior to delivery for direct installation and use.

Applications

  • Surface Water Monitoring: Lakes and rivers monitoring conductivity to assess water quality and detect pollution. Reservoir monitoring to ensure the quality of water used for drinking and irrigation. 

  • Municipal Sewage: Wastewater treatment plants monitoring sewage conductivity to optimise treatment processes and ensure compliance with discharge regulations. 

  • Industrial Wastewater: Effluent monitoring to ensure industrial effluent meets environmental standards by tracking conductivity levels. 

  • Process Control: Managing conductivity in industrial processes to maintain product quality and safety. 

  • Sewage Treatment: Treatment facilities optimising treatment processes by monitoring conductivity levels. 

  • Aquaculture: Fish farms monitoring water quality to maintain optimal conditions for fish health and growth.
