Abstract
A field device includes a housing having at least an antenna receiving bore. Field device electronics are disposed within the housing and include wireless communication circuitry configured to communicate wireless process information. An antenna assembly includes an antenna base engaged within the antenna receiving bore of the housing. The antenna assembly including an antenna operably coupled to the wireless communication circuitry. The antenna assembly is rotatable within the bore by an amount less than one full rotation, and rotation of the antenna assembly varies orientation of the antenna.
Claims22
A field device comprising:
- a housing having at least an antenna receiving bore formed integrally therein;
- field device electronics disposed within the housing, the field device electronics including wireless communication circuitry configured to communicate wireless process information;
- an antenna assembly including an antenna base sealing engaged within the antenna receiving bore of the housing to thereby seal the housing from an environment of the field device, the antenna assembly including an antenna which extends at an angle with respect to the bore and which is operably coupled to the wireless communication circuitry;
- wherein the antenna assembly is rotatable within the bore by an amount less than one full rotation, and wherein rotation of the antenna assembly varies orientation of the antenna;
- and
- the housing has a rotation stop and the antenna base has a feature, each of the rotation stop and the feature include protrusions, wherein the protrusions of the rotation stop engage the protrusions of the feature to prevent rotation of the antenna assemble beyond a given amount with respect to the housing.
