Endress+Hauser Smartec CLD18 Inductive Conductivity Sensor

The Endress+Hauser Smartec CLD18 is a compact, inductive conductivity transmitter designed for hygienic applications in the food, beverage, and pharmaceutical industries. It features a sanitary in-line design with a 2-inch hygienic fitting, ensuring compliance with strict hygiene standards such as 3-A and EHEDG. The sensor uses inductive measurement technology, which provides reliable, maintenance-free operation without electrodes, making it ideal for monitoring conductivity in processes like CIP (Clean-in-Place) systems, phase separation, and product quality control. Key benefits include high accuracy, fast response times, and integrated temperature compensation for precise readings across a wide range. It supports analog outputs for easy integration with control systems. Advantages over similar products include its robust stainless steel construction, IP69 protection rating for harsh environments, and compact size that reduces installation space. Drawbacks may include higher initial cost compared to basic conductive sensors and the need for compatible fittings.
