Claim Text:
1. A device for measuring the temperature of a beam of a vibrating beam sensor vibrating according to a flexural mode, the device comprising an additional element that vibrates according to a mode different from the flexural mode and the resonance frequency of which, as a function of the temperature, is known, said resonance frequency being substantially different from that of the beam, wherein the additional element is a resonator configured to vibrate torsionally in a resonance mode and having a torsional vibration node, said node being located in a fixing zone in the vicinity of a middle of a length of the vibrating beam, said fixing allowing heat transfers between the resonator and the beam, by virtue of which the frequency of the resonator and the variations in that frequency are representative of the mean temperature of the beam and of the variations in that temperature, respectively.
