FIELD: measurement equipment.
SUBSTANCE: invention relates to the field devices used in process control and monitoring systems, and, in particular, to field devices which use wireless data transmission. The wireless field device or the adapter for conversion of the wire field device to the wireless field device includes the housing, the first plug socket on the housing and the dismountable antenna module which includes the antenna, the second plug socket which is capable to connect and disconnect from the first plug socket, and the fairing which contains the antenna and is fixed on the second plug socket. The fairing is made from current-dissipating material which dissipates the generated static voltage without sparking at connection and disconnection of plug sockets, making it possible to separate the antenna or to install during the time of occurrence of the wireless field device in potentially hazardous (classified) zone.
EFFECT: protecting from sparking during antenna dismantling or mounting in case of operation in a hazardous zone.
