摘要:
A turbomachine (101) having a rotor, wherein the rotor comprises a central holding element (124) and rotor elements (122) which are arranged thereon, is intended to permit faster start-up without reducing the lifetime of the rotor, while permitting better predictions relating to the remaining lifetime of the rotor. To this end, a contact element (126) is arranged in a region of the rotor between the holding element (124) and the rotor element (122), wherein the contact element (126) comprises a temperature measurement device (134).
