PURPOSE:To make the detection of the temp. of a member to be detected in a vessel from the outside possible without contacting the same by fixing a displacing member by means of a fixing member which releases fixing when a prescribed temp. is attained and detecting the displacement of the displacing member with X-ray devices. CONSTITUTION:A displacing member 5 which absorbs X-rays, a fixing member 4 which is provided to a member 2 to be detected contained in a vessel 1, fixes the member 5 to a prescribed position and releases the fixing of the member 5 when temp. exceeds a prescribed temp., and X-ray devices 6, 7 which detect the member 5 are provided. For example, the fixing member 4 which consists of a resin or the like melting at prescribed temp. and is buried therein with the displacing member 5 such as lead is fixed to the upper part of the inside surface of a conductor 2 near the juncture 3 of the conductor 2 which is contained in the vessel 1 and is applied with high voltage. The image of the member 5 is projected with the X-ray devices 6, 7 provided on the outside of the vessel 1. |
