摘要： A system may include a hose assembly; a sensor device; and a controller. The hose assembly may be configured to be connected to a hydraulic circuit of a machine. A first layer, of a hose of the hose assembly, may be configured to transport a hydraulic fluid. A second layer, of the hose, may comprise a tracer material that is configured to be released into the hydraulic fluid when the first layer is experiencing a failure. The sensor device may be configured to detect the tracer material in the hydraulic fluid, and generate sensor data indicating that the tracer material has been detected. The controller may be configured to determine that the hose assembly is experiencing the failure based on the sensor data and cause an action to be performed based on determining that the hose assembly is experiencing the failure.
