FIELD: machine building.SUBSTANCE: invention relates to a closure element or fastening element for inserting into bore (12) in component (11), such as into a bore in an engine, a valve block, a hydraulic unit or a container. Fastening element is equipped with at least one electric element (20) which is arranged in element (10) or on element (70), intended for transmitting and/or receiving electric signals. Element (10) is equipped with main housing (15), shaped as a sleeve, which can be inserted into bore (12), and outer circle of housing in mounted state tightly adjoins inner surface of bore (12), and expanding housing (16), which can hold apart said main housing (15) in bore (12). In fitted state,electric element (20) is advantageously positioned in such a manner that said electric element is adjacent to chamber (12') formed in bore (12) and is therefore in contact, for measuring purposes, with medium contained in bore (12).EFFECT: using invention in addition to function of closing and/or fixation of said element ensures execution of one or more measurements.15 cl, 11 dwg |
