To climatic fluctuations is less sensitive, the temperature controlled a piezoelectric resonator.

摘要

The present invention relates to a pilot thermostatically controlled to a piezoelectric resonator (11), not very sensitive to climatic variations. The piezoelectric resonator is inserted in a thermostatted enclosure (6) comprising a body (10) and a cover (9). br / in order to improve the stability in the frequency of the pilot, when the temperature, pressure and the humidity rate vary it seals the thermostatted enclosure (6). The cover (9) and the body (10) of the enclosure are sufficiently rigid not to deform under the action of the variations in external pressure to the chamber (6). br / of the seal, a seal of the glue or of the solder provide sealing between the cover (9) and the body (10) of the thermostatically controlled containment. & br / applications to the pilot frequency quartz stable over a wide temperature range.
