CS3540 Industrial Conductivity Sensor
Key advantages include excellent resistance to corrosion and coating, making it suitable for wastewater, aggressive chemicals, and high-solids slurries where platinum electrodes would rapidly degrade. Its rugged construction often allows for high-pressure and high-temperature operation. However, its primary limitation is a narrower measurement range compared to premium platinum cells, as graphite can polarize at very high conductivities.The graphite conductivity electrode is a robust and widely used sensor designed for measuring the electrical conductivity of aqueous solutions in demanding industrial, environmental, and process control applications. It offers a cost-effective and durable alternative to traditional platinum electrodes, particularly in media where fouling, abrasion, or chemical attack are concerns. When paired with a high-quality transmitter, the graphite conductivity electrode provides a reliable balance of performance and longevity for challenging on-line monitoring tasks, forming a critical component in modern water quality management. -
CS3601C Conductivity Sensor RS485 EC Probe
The graphite conductivity electrode is a robust and widely used sensor designed for measuring the electrical conductivity of aqueous solutions in demanding industrial, environmental, and process control applications. It offers a cost-effective and durable alternative to traditional platinum electrodes, particularly in media where fouling, abrasion, or chemical attack are concerns.
The electrode typically consists of two precisely spaced graphite elements (cells) encased within a chemically resistant body, such as PPS or epoxy. Graphite's inherent conductivity and porous structure provide a large effective surface area, ensuring stable signal generation. When an alternating current is applied, the ions in the solution complete the circuit between the electrodes; the measured conductance is directly proportional to the ion concentration. A built-in temperature sensor (usually a Pt1000 RTD) is essential for automatic temperature compensation, correcting readings to the standard reference of 25°C.
These electrodes are integral to systems monitoring water purity (e.g., RO permeate, ultrapure water), controlling chemical dosing in wastewater treatment, and managing concentration in industrial processes like cooling towers or food & beverage production. When paired with a high-quality transmitter, the graphite conductivity electrode provides a reliable balance of performance and longevity for challenging on-line monitoring tasks, forming a critical component in modern water quality management. -
