In the bottled soft drink industry, the use of pipelines is common; however, undetected leaks can lead to product loss or damage to the facilities. Therefore, the objective of this research is to propose a sensor element capable of detecting leaks and pinpointing their exact location as quickly as possible. A cable-type sensor was developed, composed of copolymers and nichrome wires, designed to detect leaks of carbonated soft drinks in processing pipelines. The copolymer was synthesized using 70% poly (n-butyl acrylate) and 30% poly (acrylic acid) through radical emulsion polymerization. The ingredients were combined in a two-neck flask, nitrogen was introduced via bubbling, and the reaction mixture was maintained at 60–70 °C under stirring to initiate polymerization. The cable prototype features two embedded nichrome wires that form an electrical detection system, utilizing the conductivity of the beverage’s water content to detect and locate leaks with high precision (error margins of ±0.0002% within the first 3 minutes). Ambient humidity does not affect the sensor's sensitivity. Keywords: Leak Detection, Carbonated Beverages, Copolymers, Sensor Systems, Pipeline Monitoring.
