The conductivity value indicates how well a material conducts electric current. In the water, food and beverage industries, as well as in other sectors, this value is used as an important measured parameter in quality assurance. It contributes, for example, to the optimisation of CIP processes or to the quality monitoring of ultrapure water. What is more, conductivity can also be used as an indicator for phase separation.

The LDL100 is the right choice to identify process phases. The differentiation between media and resulting process phase identification plays a decisive role, especially in the food industry. Cleaning agents, rinsing water and products in the process pipes have different conductivity values and can therefore be easily and reliably detected. This ensures unambiguous tracking at all times.
The LDL101 conductivity sensor is the right choice where the purity of water is crucial for product quality or process reliability. The sensor detects the conductivity of water from a value of 0.04 µs/cm. This makes it ideal for applications in water filtration where purified water of all levels is used. Possible applications here are water treatment, parts cleaning and critical supply systems (cooling water).
With a conventional analogue output, a large measuring range is scaled to 4..20 mA. As a result, the smallest changes in conductivity can often not be directly detected. This can lead to residual amounts of chemicals going undetected in rinse water or products, and in the worst case even result in product recalls. With IO-Link, however, the resolution of the conductivity value is always scaled to suit the used measuring range, so that the highest possible accuracy is guaranteed at all times.
