SENSE AND HOLD CIRCUIT FOR HOSE ASSEMBLY |
摘要 |
A monitoring circuit for detecting degradation of a hose assembly a hose assembly and a hose assembly incorporating such a monitoring circuit are disclosed. The monitoring circuit includes a voltage source connected to a first connection location of a hose assembly. A capacitor is electrically connected between the second connection location connected to the second conductive layer of a hose assembly and a ground. The capacitor is selected such that a change in resistance of the hose assembly changes a voltage carried by the capacitor. The monitoring circuit includes a voltage sampling circuit configured to periodically detect a voltage at the capacitor. Upon detecting a change in the voltage above a predetermined threshold, the voltage sampling circuit generates an alarm indicative of potential failure. |
