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. -

CS3753C Electrical Conductivity Sensor 4-20ma
electrode type liquid level meter uses the electrical conductivity of materials to measure high and low liquid levels. It can also be used for liquids and wet solids with weak electrical conductivity. The principle of the boiler electric contact level meter is to measure the water level according to the different conductivity of steam and water. The electric contact water level meter is composed of a water level measuring container, an electrode, an electrode core, a water level display lamp and a power supply. The electrode is mounted on a water level container to form an electrode water level transmitter. The electrode core is insulated from the water level measuring container. Because the conductivity of water is large and the resistance is small, when the contact is flooded with water, the short circuit between the electrode core and the container shell, the corresponding water level display light is on, reflecting the water level in the drum. The electrode in the steam is small because the conductivity of the steam is small and the resistance is large, so the circuit is blocked, that is, the water level display lamp is not bright. Therefore, a bright display light can be used to reflect the level of the water level.
