Abstract

PURPOSE: To quicken data processing and to reduce its electric power consumption by facilitating multipoint measurement by leading output signals out of temperature- measuring elements in a rotor by way of a slip ring through switching operation and then by inputting them to a data processor.
CONSTITUTION: As a rotor coil is fed with electric current through the operation of rotor 1, a temperature rises and electromotive force is generated at each temperature-measuring element 3 in proportion to the temperature. Conductors 21 extending to respective measurement points are automatically changed over by controller 24 and change-over unit 20 and a signal obtained by amplifying the voltage of the electromotive force of the element 3 is led out by way of slip ring 2 and, after being amplified by controller 24, input to data processor 28 by way of recorder 27. Changeover unit 20 has 32 terminals at its input side and provides 32-point measurement by use of 11 slip rings 2. Thus, the multipoint measurement is made easy and the data processing can be quickened and reduced in power consumption by the data processor.
