ABSTRACT:
There is disclosed a sensing apparatus for monitoring a structure subject to wear, and providing an automatic indication upon the thickness of such structure being worn to a predetermined, minimum operable value. Such apparatus includes a sensing device that is insertable into a recess in one surface of structure to a depth corresponding to the predetermined minimum thickness; and a coaxial electrical cable including an inner conductor, a heat resistant covering, and an outer metallic tubular sheath that is preferably corrugated. One end of the coaxial cable is shaped as a loop and is positioned within the sensing device in the vicinity of the bottom face thereof, while the other end of the cable is connected to a contact assembly to which is connected a measuring circuit for automatically ascertaining the condition of the cable components within the sensing device.
