A wireless process communication adapter (14, 30) is provided. The adapter (14, 30) includes a housing (120) having a plurality of openings (150, 152). An end cap (124) is coupled to a first opening (150) of the plurality of openings (150, 152). A field device coupling (122) is disposed at the second (152) of the plurality of openings (150, 152). The housing (120), end cap (124) and field device coupling (122) define a chamber (130) therein. At least one circuit board is disposed within the chamber (130), the circuit board (132, 134) has wireless communication circuitry disposed thereon and is coupleable to a field device (12) through the field device coupling (122). In one aspect, substantially all remaining volume in the chamber is filled with a solid material (136). In another aspect, an explosion-proof barrier (164) is provided in the field device coupling (122). Combinations of the aspects are also provided.

La présente invention concerne un adaptateur de communication (14, 30) pour traitement radio. L'adaptateur (14, 30) comporte un logement (120) comportant une pluralité d'orifices (150, 152). Un capuchon d'extrémité (124) est couplé à un premier orifice (150) de la pluralité d'orifices (150, 152). Un coupleur de dispositif portable (122) est disposé au niveau du deuxième orifice (152) de la pluralité d'orifices (150, 152). Le logement (120), le capuchon d'extrémité (124) et le coupleur de dispositif portable (122) définissent intérieurement une chambre (130). Au moins une carte à circuit imprimé est disposée à l'intérieur de la chambre (130). La carte à circuit imprimé (132, 134), qui est équipée de circuits de radiocommunication, peut se coupler à un dispositif portable (12) au moyen du coupleur de dispositif portable (122). Dans un aspect de l'invention, sensiblement tout le volume restant à l'intérieur de la chambre est comblé d'un matériau solide (136). Dans un autre aspect, une barrière antidéflagrante (164) est placée dans le coupleur de dispositif portable (122). Ces aspects peuvent se combiner.
