Abstract
A roller comprises a thermocouple delivering a voltage signal which is converted by converting mechanism carried by the roller into a stabilized signal whose magnitude is independent of the resistance of the output circuit. The stabilized signal is transmitted to the fixed part of the measuring circuit by a device comprising slip rings and fixed collectors. The converting mechanisms are disposed in a case of the roller and provided with an air cooling device. The air is channelled in the case by annular supports and frames carrying the converting mechanism. Application in the measurement of the temperature of flat products travelling through a continuous annealing furnace.
Claims5
A roller for supporting and/or driving flat products or sheets comprising at least one thermocouple, and converting means carried by the roller, comprising, for said at least one thermocouple, a converter converting a voltage signal delivered by said at least one thermocouple into a stabilized current whose magnitude is independent of the resistance of a circuit in which said current flows, and a set of slip rings and fixed collectors, the rings of said set being connected to outputs of said converter so that the stabilized current flows in said set of slip rings and fixed collectors.
