4.2 Conductive Detection Method

Detecting liquid using the conductive method involves measuring the electrical conductivity of the liquid. This method is based on the principle that liquids, especially those containing ions (such as water with dissolved salts), can conduct electricity. Two electrodes, typically made of conductive materials like stainless steel or copper, are placed where liquid presence needs to be detected. When the liquid comes into contact with the electrodes, it completes the electrical circuit, allowing current to flow between them. The presence of ions in the liquid facilitates this flow of current.
