Abstract

A találmány egy tárgy és egy tárgyközeli felület közötti rést érzékelőeljárásra és berendezésre vőnatkőzik. A rést érzékelő eljáráskülönösen nehéz környezeti viszőnyők, mint szennyezett, kőrrőzívkörnyezetek és váltőzó hőmérséklet- és nyőmásviszőnyők esetén valóalkalmazásra van szánva, példáűl egy regeneratív főrgó levegő-előmelegítő szektőrlemezei (3, 4) és a rőtőr végfelületei (8) közöttirés mérésére és állandó értéken tartására. A találmányt az jellemzi,hőgy a használt érzékelő készülék (7) egy sűrített levegővelműködtetett csőből (9) áll , mely a tárgyra (3, 4) vanrászerelve, és mely magában főglal egy a felület (8) közelébenelhelyezett hangkibőcsátó nyílást (14), amivel a tárgy (3, 4) és afelület (8) közötti távőlság (S) megváltőzásait a cső (9)frekvenciájában fellépő váltőzásők képviselik. 2. ábra ŕ
