Quartz thermometer |
摘要 |
A quartz thermometer which emits a signal, the frequency of which is a substantially linear function of temperature. The thermometer comprises a quartz resonator provided with electrodes disposed on the margins of the upper and lower main surfaces, parallel to the length direction. The electrodes are supplied with electric current so as to cause the resonator to vibrate torsionally. The length of the resonator is substantially parallel to the X axis of the quartz crystal. An electronic circuit is responsive to the signal emitted by the resonator for producing an output representative of temperature.
