second embodiment

[0037]the invention is shown in FIGS. 5 and 6. In this embodiment, the electronic card 30 possesses a portion 30.1, which is substantially triangular in this example, that extends outside the housing 20 and that has extending therein an antenna wire 36.1 that is connected to the radio transceiver 36.

third embodiment

[0038]In a third embodiment, shown in FIG. 7, the second of channels 33 are associated with a heater device, specifically in the form of a resistor wire 70 embedded in the card 30 and spiral wound around each second channel 33. The wire 70 is connected to the poles of a second rechargeable battery 71 via a current regulator unit 72 that is controlled by the microcontroller 35. Advantageously, the second rechargeable battery 71 is connected to the converter 38. The resistor wire 70 thus serves to heat the fluid passing through the second channels 33 from the first volume 3 to the second volume 4 and to keep its temperature above the dew point. This heating thus serves to ensure that the fluid penetrating into the enclosure 42 is dry, while concentrating any zones of ice formation in the first volume 3 at the peripheries of the first channels 33 where the fluid has not been heated.

[0039]Naturally, the invention is not limited to the embodiments described, but covers any variant coming...

Abstract

A pressure measurement device (1) comprising a housing (20) extending around an electronic card (30) provided with a pressure sensor (40);the housing (20) co-operating with a first face (31) of the electronic card (30) to define a first sealed volume (3);the housing (20) also co-operating with a second face (32) of the electronic card (30) that is opposite from the first face (31) to define a second sealed volume (4);the housing (20) including at least one first channel (24) putting the medium (5) outside the housing (20) into fluid flow communication with the first sealed volume (3);the electronic card (30) including at least one second channel (33) putting the first volume (3) into fluid flow communication with the second volume (4); andthe connection between the housing (20) and the electronic card (30) being arranged to allow relative movement between the housing (20) and the electronic card.

Description

FIELD OF THE INVENTION[0001]The present invention relates to measuring pressure, and more particularly to measuring pressure in an aircraft wheel.BACKGROUND OF THE INVENTION[0002]Conventionally, an aircraft wheel comprises a cylindrical rim carrying a tire that co-operates with the rim to define an inside volume filled with a fluid under pressure, generally air or a fluid comprising a majority of nitrogen together with various components of air. After each landing, the pressure of the air contained in the wheel is measured by using a pressure measurement device mounted on an inflation valve secured to the rim. The rim generally contains a stack of brake disks called a heat pack that gives off a significant amount of heat when braking the aircraft (temperatures higher than 500 degrees Celsius). This heat requires the use of specific materials and assembly techniques, which make the manufacture of such a pressure sensor very expensive. Furthermore, the exposure of the sensor to high t...
