Abstract
A fixing element, a use of a sensitive element to detect a flow of heat on the inside of mechanical organs; wherein the fixing element, in particular a screw or a stud, has a body and a sensitive element, which is designed to detect a difference of temperature between a first and a second area of the body of the fixing element, so as to determine, as a function of said difference of temperature, a flow of heat that flows through the fixing element and the mechanical organ where it is installed.
Claims13
A fixing element comprising a body, which is cylindrical and has a longitudinal axis, and a sensing element, which detects a difference of temperature between a first area and a second area of said body;
- wherein said first area and second area are spaced apart along the longitudinal axis of the fixing element, wherein said body comprises a cavity extending along the longitudinal axis of the body and having a cross-section with a circular shape, said cavity housing said sensing element;
- wherein said sensing element comprises, in turn, a first conductor and a second conductor, which are connected to one another in correspondence to a first thermocouple junction and a second thermocouple junction in correspondence to the first and, respectively, the second area of said body;
- wherein the first thermocouple junction and the second thermocouple junction detect a signal concerning the difference of temperature between said first and second area;
- wherein, the sensing element comprises a support, which is made of a flexible material;
- wherein the support is bent so as to form a sensitive cylinder inserted in said cavity of the fixing element;
- wherein said first thermocouple junction and said second thermocouple junction are formed on the support so as to be arranged in correspondence to the first area and the second area, respectively.
