(FR) MONTRE FOURNISSANT UNE INDICATION BAROMETRIQUE OU ALTIMETRIQUE, ET SON PROCEDE DE FABRICATION
Abstract
(EN)
The invention concerns a wristwatch comprising in its case a resistive piezoelectric pressure and temperature sensor (26) exposed to a pressure chamber (42) communicating with the outside environment, for measuring ambient pressure. In order to provide individual calibration depending on temperature followed by a permanent correction of the sensor pressure signals, the latter is fixed to the lower surface of a printed circuit card (30) bearing the electronic circuits (35) processing the sensor signals. The calibration parameters are recorded in a non-volatile memory (36) of said circuits. A rigid and sealed separating partition (43) forms an internal floor separating the pressure chamber (42) from the watch sealed part.
(FR)
La montre-bracelet comporte dans son boîtier un capteur piézo-résisistif de pression et de température (26) qui est exposé à une chambre de pression (42) communiquant avec l'extérieur, pour mesurer la pression ambiante. Pour permettre un étalonnage individuel en fonction de la température et ensuite une correction permanente des signaux de pression du capteur, ce dernier est fixé à la face inférieure d'une carte à circuits imprimés (30) qui porte les circuits électroniques (35) traitant les signaux du capteur. Les paramètres d'étalonnage sont enregistrés dans une mémoire non volatile (36) desdits circuits. Une cloison de séparation (43) rigide et étanche forme un fond intérieur qui sépare la chambre de pression (42) de la partie étanche de la montre.
