REMOVABLE APPARATUS FOR DETERMINING THE TEMPERATURE INSIDE A VESSEL

摘要

A temperature sensor is positioned in an opening of a vessel wall by a holding mechanism which contains a sealing means that cooperates with the temperature sensor to close off the opening in a fluid tight manner. To that end of the temperature sensor which is inside the vessel, there is releasably attached a plug member which is drawn by the temperature sensor into engagement with the sealing means as the temperature sensor is withdrawn therefrom. Thereafter, the temperature sensor is disconnected from the plug member and the latter is left in engagement with the sealing means while the temperature sensor is removed from the vessel, for example, for replacement.
