METHOD OF MEASUREMENT OF TEMPERATURE OF ROTATING OBJECTS BY THERMOCOUPLE Russian patent published in 1997 - IPC

FIELD: measurement technology, transmission of electric signals from moving objects to immobile measurement equipment. SUBSTANCE: electrical coupling of moving object with measurement circuit is accomplished with the use of sliding contact made from two electrodes insulated one from another, simultaneously sliding along moving object and forming thermocouples with it which are placed into electric circuit from which output signal coming from brushes is picked off. Materials of electrodes of thermocouples are so chosen that they create thermal emf-s of opposite sings. Thermocouples are placed into two active arms of bridge circuit. Balancing of circuit is achieved by adjustment of active resistances in two other arms of bridge. EFFECT: enhanced functional reliability of method. 1 dwg
