DEVICE FOR MEASURING THE TEMPERATURE OF A VIBRATING BEAM AND APPLICATION TO THE IMPROVEMENT OF THE PRECISION OF MEASUREMENT OF A VIBRATING-BEAM SENSOR |
摘要 |
The invention is a device for measuring the temperature of the vibrating beam of a vibrating-beam sensor. It comprises a resonator (10) vibrating in torsion in resonant mode and exhibiting a torsional vibration node (N), said node being its zone of fixing in the vicinity of the middle of the length (L3) of the vibrating beam, said fixing allowing thermal transfers between the resonator and the beam. The frequency of the resonator and the variations of this frequency are representative respectively of the mean temperature T of the beam and of the variations of this temperature T, the effects of which may be compensated by a model. |
