Conductivity BTS50085-1TMA sensors are sensors generally used in laboratories, industrial production and detection fields to measure the conductivity of various solutions such as ultrapure water, pure water, drinking water, sewage, or the overall ion concentration of water samples. It provides a direct indication of the ionic content in the solution, which is essential for monitoring water quality in various applications such as industrial processes, environmental monitoring, and water treatment.
Structure
Conductivity BTS50085-1TMA sensors typically consist of electrodes or coils that are housed in a protective body made of materials resistant to corrosion and fouling, such as stainless steel or high-grade plastic. Contacting sensors feature electrodes that directly interface with the solution, while inductive sensors contain a pair of coils encased within a non-conductive housing, with one coil generating a magnetic field and the other detecting the induced current. Many conductivity sensors also incorporate a temperature sensor to allow for temperature compensation.

Classification
Contacting Conductivity Sensors
Contacting conductivity BTS50085-1TMA sensors measure conductivity by directly applying a voltage to electrodes in contact with the solution. The current flowing between these electrodes is proportional to the solution's ionic content. These sensors are commonly used in applications where the solution is relatively clean and free of fouling agents, such as in pure water systems, boiler feedwater, and certain industrial processes.
Inductive (Toroidal) Conductivity Sensors
Inductive conductivity sensors, also known as toroidal or electrodeless sensors, operate without direct contact between the sensor and the solution. Instead, they use magnetic fields to induce a current in the solution. This type of sensor is ideal for applications with highly conductive or dirty solutions, where fouling or coating of the sensor electrodes would be an issue.
Two-Electrode Conductivity Sensors
Two-electrode conductivity sensors feature a pair of electrodes that directly measure the conductivity of the solution. They are suitable for low to moderate conductivity ranges and are often used in water treatment plants, laboratories, and aquariums. However, they can be prone to polarization effects and fouling, which may require regular maintenance.
Four-Electrode Conductivity Sensors
Four-electrode conductivity sensors, also known as four-pole sensors, use two electrodes to apply an alternating current and two additional electrodes to measure the voltage drop. It helps minimize polarization and electrode fouling effects, providing more accurate and stable measurements over a wider range of conductivity levels. They are commonly used in industrial applications, such as in chemical manufacturing and food processing.
Temperature-Compensated Conductivity Sensors
Temperature-compensated conductivity sensors incorporate a temperature sensor to adjust the conductivity reading based on the solution's temperature. Conductivity is highly temperature-dependent, and these sensors measure across varying temperatures. They are essential in applications where temperature fluctuations are common, such as in outdoor environmental monitoring, industrial processes, and aquaculture.
Operating Guide
To use a conductivity sensor, you should make the sensor fully contact with the substance being measured. Connect the conductivity electrode to the sensor by aligning the notch on the BNC connector with the protruding part of the sensor's interface and tightening it securely. Before and after use, rinse the electrodes with distilled water and blot them dry with filter paper to maintain accuracy and cleanliness.
Conclusion
Overall, conductivity sensors are essential tools for measuring the ionic content of a solution, providing valuable data for various applications in water quality monitoring, chemical production, and environmental science. Therefore, proper use and maintenance of conductivity sensors benefits to scientific and industrial settings.
