Claim:
1. A monitoring circuit configured to detect degradation of a hose assembly, the circuit comprising: a voltage source connected to a first connection location of a hose assembly, the hose assembly including a hose having a first conductive layer and a second conductive layer, the first connection location electrically connected to the first conductive layer, wherein the second connection location is electrically connected to ground; a capacitor electrically connected to the hose assembly via a differential voltage detection circuit, wherein a difference between a voltage at the voltage source and a voltage across the hose is captured by the capacitor; a voltage sampling circuit configured to periodically detect a voltage at the capacitor, wherein, upon detecting a change in the voltage above a predetermined threshold, the voltage sampling circuit is configured to generate an alarm indicative of potential failure of the hose assembly.
