Conductivity measurement is widely used in industrial and environmental applications as a simple and inexpensive way to monitor and to control the ionic concentration in a solution:

Home appliances

conductivity measurement in coffee machines
When does a coffee machine need descaling?

The conductivity of water can significantly influence the taste of beverages such as tea and coffee. By using a conductivity sensor, variations in the water can be monitored, allowing for adjustments in the brewing process of coffee or the steeping of tea to achieve optimal flavor.


Additionally, the conductivity of the water is directly related to the descaling interval of the equipment. A conductivity sensor can provide an indication of when descaling is necessary. After the cleaning process, the sensor can also detect any residual cleaning agents, ensuring that the equipment is thoroughly rinsed and safe for use.

Conductivity sensors for pure water monitoring

Conductivity measurement in Fuel Cells
Fuel cells and e-mobility

The continuous monitoring of the electrical conductivity of the coolant plays a crucial role. This real-time data collection is essential for ensuring that the coolant remains free from contaminants, which could otherwise lead to short circuits or leakage currents. By maintaining the purity of the coolant, these measurements help to prevent potential electrical faults that could compromise the system's integrity. 

Conductivity element for low conductivity measurements

Moreover, the monitoring contributes significantly to the longevity and reliable operation of the entire system. By proactively identifying and addressing any issues related to coolant contamination, the risk of unexpected breakdowns is minimized. This not only enhances the overall performance and efficiency of fuel cells and charging stations but also ensures a safer and more dependable e-mobility experience for users.

Determine soil quality with conductivity monitoring

EC Value of water and soil
Agriculture

Conductivity sensors can play a significant role in agriculture, providing valuable data for optimizing crop management, improving efficiency as well as supporting sustainable farming. Conductivity measurement data of soil monitoring allows farmers to make informed decisions about nutrient management (fertilization) as well as watering and sprinkler irrigation. Regular conductivity monitoring prevents land deterioration through over-salinization, soil compaction, or nutrient imbalances, enabling timely interventions to mitigate potential problems before they have an impact on the harvest and the overall quality of the soil.

Water quality monitoring with conductivity sensors

Conductivity sensors are essential tools in ensuring that drinking water meets safety standards in water treatment. On one hand, they help detect the presence of contaminants in drinking water, such as dissolved salts, heavy metals, and other pollutants.
On the other hand, conductivity sensors are instrumental in optimizing water treatment processes. They provide valuable data that can be used to determine the precise dosage of chemicals needed to remove impurities from the water. This ensures that the treatment process is both efficient and effective, resulting in high-quality drinking water.

Industrial process monitoring
Conductivity monitoring in the food & beverage Industries

In the food processing industry, continuous conductivity monitoring helps manufacturers maintain consistent product quality and the taste profiles consumers expect. By tracking conductivity levels in real time, they can quickly identify deviations in liquid composition and take corrective action before quality is affected. 

Conductivity measurement also plays a key role in cleaning processes. It helps verify that cleaning procedures have been carried out effectively and that no residues from cleaning agents or other substances remain in the system. This supports reliable sanitation and reduces the risk of contamination before production resumes

Bio or chemical processing

Monitoring chemical concentrations
Bio or chemical processing

In bio or chemical processes, conductivity sensors play an important role in supporting the control of various biological and chemical reactions. These sensors are integral to maintaining the desired conditions within reactors, ensuring that the reactions proceed efficiently and effectively. By continuously monitoring the conductivity, these sensors help in detecting any deviations from the optimal conditions, thereby enabling timely interventions to correct any issues.

In the pharmaceutical industry, the measurement of ion concentration during drug manufacturing processes is crucial for maintaining stringent quality and purity standards. Furthermore, in bioreactors, conductivity sensors are for example used to determine the availability of nutrients, which is critical for the growth and productivity of biological cultures.

Medical applications

Blood monitoring
Monitoring of bodily fluids

Conductivity sensors are essential in dialysis applications to ensure the safety and effectiveness of treatments. They monitor the ionic composition of the dialysate, verify the proper mixing of the dialysate solution, and ensure the purity of the water used in dialysis. These sensors also detect equipment malfunctions, providing real-time data for immediate adjustments and therefore significantly enhance patient safety.
In addition to their role in dialysis, conductivity sensors are also used in urine monitoring to measure the concentration of electrolytes in urine. When integrated with urine output measurements, these sensors provide a comprehensive overview of a patient's renal health. This information is crucial for assessing kidney function and detecting conditions such as acute kidney injury.
