Selecting the correct cell constant (e.g., K=0.1 cm⁻¹ for high purity water, K=1.0 cm⁻¹ for general use) is critical for optimal accuracy. As the primary interface with the process, the conductivity electrode, when paired with a quality transmitter, forms an indispensable system for real-time, reliable water quality and process control. -
CS3732 Conductivity Sensor
onductivity electrode is a fundamental sensor designed to measure the ability of an aqueous solution to conduct electrical current, which directly correlates with its total concentration of dissolved ions. This key parameter is essential for assessing water purity, controlling chemical processes, and monitoring environmental compliance across industries like pharmaceuticals, power generation, food and beverage, and wastewater treatment.
The core of the electrode is a measurement cell containing at least two conductive elements. When an alternating current is applied, the ions in the solution complete the circuit between these elements. The resulting conductance is measured and, along with the cell's geometric constant (cell constant, K), is used to calculate conductivity. Modern electrodes are almost always integrated with a temperature sensor (typically a Pt100 or Pt1000 RTD) for automatic compensation, as conductivity is highly temperature-dependent. Common designs include two-pole cells for general use and four-pole (or four-electrode) cells, which use separate current and voltage rings to minimize polarization effects and extend measurement range, especially in high-conductivity applications. -

CS3501C Conductivity Sensor Analyser
The electrode typically features two graphite elements (cells) with a defined surface area and spacing, housed within a durable, chemically resistant body. When immersed, an alternating current is applied to prevent polarization. The ions in the solution facilitate current flow between the electrodes, generating a signal proportional to the solution's conductivity. A built-in temperature sensor (e.g., Pt1000) is essential for automatic compensation, as conductivity is highly temperature-dependent. Modern versions often incorporate multiple cells (like four-electrode designs) to extend range and minimize fouling errors.
The primary advantage of graphite over platinum is its superior cost-effectiveness and robustness in harsh or fouling-prone environments, such as wastewater, cooling towers, or chemical processes where abrasion or coating is a concern. However, graphite may have limitations in very high-precision or ultra-pure water applications compared to advanced platinum cells. -
