LDL200 Inductive Conductivity Sensor 100-1,000,000 µS/cm G1 Aseptoflex | IFM

The Original New IFM LDL200 Inductive Conductivity Sensor is a high-performance hygienic sensor designed for precise measurement of conductivity and temperature in conductive liquids. Part of the LDL2xx family, this sensor is specifically engineered for CIP (Clean-in-Place) monitoring in the food and beverage industry, enabling detection of cleaning agent concentration, rinse water contamination, and product residue validation. Featuring an inductive measuring principle, the LDL200 operates without electrodes, eliminating polarization effects and scaling issues common with conductive sensors. The fully welded stainless steel housing with G1 Aseptoflex Vario process connection and IP68/IP69K protection ensures reliable operation in harsh sanitary environments. IO-Link communication provides loss‑free digital transmission of conductivity and temperature values, enabling real‑time process optimization and significant reductions in cleaning agent usage, energy consumption, and water waste.
