FIELD: measurement technique.
SUBSTANCE: invention refers to facilities intended for protection of field instruments, such as level gages, manometres, thermometres etc. result is provided due to the fact that protective body contains the first and the second modules. The first module of the body has the first volume and the fist potential bus and the second module of the body has the second volume and the second potential bus. Herewith, the first and the second modules of the body are made able to be connected in operation state in such a way that the first and the second volumes form one common volume. Additionally, the first and the second potential buses are made able to be connected in such a way that the first and the second potential buses in connected operation state form one common potential bus for common volume.
EFFECT: providing effective protection of instruments against environmental impacts, increase in reliability of instrument operation in field conditions and operation convenience improvement.
