Zusammenfassung:The invention relates to a device for measuring the temperature in the discharge area of a fuel and for estimating the erosion of the burning pipe. According to the invention, the device consists of a series of thermocouples consisting of a fuel carrying pipe (T1) and a pipe (T2) comprising several successive sections (Tr1, Tr2 and Tr3) electrically and mechanically connected to the fuel carrying pipe (T1), the electric connection being achieved by some welding points (Sud1, Sud2, Sud3), and, in the space between the two pipes (T1 and T2), air being injected, the thermocouple assembly thus formed being provided with some terminals for picking up the generated electric signal based on which the temperature of the fuel discharge zone is determined and the pipe wear is estimated. Invenţia se referă la un dispozitiv de măsurare a temperaturii zonei de evacuare a unui combustibil, şi de estimare a eroziunii ţevii de ardere. Dispozitivul conform invenţiei este alcătuit dintr-o succesiune de termocupluri formate dintr-o ţeavă (T1) purtătoare de combustibil şi dintr-o ţeavă (T2) alcătuită mai multe tronsoane (Tr1, Tr2 şi Tr3) succesive, conectate electric şi mecanic la ţeava (T1) purtătoare de combustibil, conectarea electrică fiind realizată prin nişte puncte de sudură (Sud1, Sud2, Sud3), iar în spaţiul dintre cele două ţevi (T1 şi T2) fiind injectat aer, ansamblul de termocupluri astfel format fiind prevăzut cu nişte borne pentru culegerea semnalului electric generat, semnal pe baza căruia se determină temperatura zonei de evacuare a combustibilului, şi se estimează uzura ţevii.
