FIELD: measurement technology, parallel follow-up test and recording of measurements of temperatures on various sections of rotary mechanisms and systems both in process of their adjustment and operation. SUBSTANCE: gear for multipoint contactless temperature control of rotary objects has distribution unit, selecting amplifying unit, controlled key stages, synchronization unit, ring switch. Distribution unit is connected to input of selecting amplifying unit. The latter is connected to functional inputs of controlled key stages. Synchronization unit is connected with use of capacitors to internal inputs of group of links of ring switch. Ring switch is coupled to manipulator inputs of group of controlled key stages. Outputs of group of controlled stages are connected through groups of detecting cells to inputs of multichannel recorder. Thanks to addition of groups of thermocouples connected to plate electrodes of rotor parts of distribution unit gear shows increased noise immunity and resolving power of parallel recording of local temperatures under forced thermal testing modes of rotary systems. EFFECT: increased noise immunity and resolving power of parallel recording of local temperatures under forced thermal testing modes. 1 dwg
