ABSTRACT:
A temperature sensor indicates imminent mechanical failure of a device by detecting a sharp rise in temperature of the device above a normal operating temperature range. The sensor is a flexible container filled with a signal fluid and closed by a plug having a melting point which is above the normal operating temperature range of the device. Tube flexure allows it to conform substantially to the shape of a surface on the device being monitored. Flexing the tube changes its internal pressure but has no effect on the plug, which responds only to changes in temperature.
