Arrangement for monitoring the temperature of a moving component: a stationary measuring device including an oscillator; a sensor on the moving component is moved past the measuring device; the sensor includes a coil that is outside the moving component and a cold conductor that senses temperature and changes its impedance in response to temperature changes and that is inside the component and electrically connected to the coil, whereby the coil is effectively short circuited or effectively open on the different sides of a preset temperature level sensed by the cold conductor, and the effective condition of the coil is sensed by the measuring device; a capacitor may be placed in series with the coil; the coil is helical and is in a plane; the coil and the cold conductor and the connecting leads are held in place by an insulating substance; specifics of the sensor body configuration are disclosed.
