Early Detection of Internal Leakage in Hydraulic Actuator

– Hydraulic systems are widely used in industrial machines such as excavators, cranes, and manufacturing equipment. One of the major issues in hydraulic actuators is internal oil leakage, which reduces system efficiency and increases maintenance cost. This paper presents a sensor-based monitoring system for early detection of internal leakage. The system uses a liquid level sensor, microcontroller, and relay module to continuously monitor oil levels. When leakage is detected, the system automatically shuts down the pump and alerts the operator. A prototype model was developed using embedded systems and Python-based monitoring. The results show that the system effectively detects leakage and prevents damage. This method provides a simple, cost-effective, and reliable solution for hydraulic system safety.
