The NCS series of capacitive limit switches are a type of liquid level sensor for the food industry that uses a capacitive sensor to measure the dielectric constant of media such as syrup, fruit juice, alcohol and oils.
This document provides technical specifications, application examples, and installation advice for the Negele NCS-x1, NCS-x2, NCS-L-11, and NCS-L-12 capacitive limit switches. These sensors are designed to detect media with low or no water content, such as syrups, fruit concentrates, alcohols, and oils, by measuring changes in dielectric constant (Dk). The devices feature hygienic designs compliant with FDA standards and 3-A Standards, suitable for CIP/SIP cleaning processes up to 143 °C.
