ABSTRACT:
The instant invention relates to a protection box to be installed on a measuring instrument assembly in a process plant. The box includes two identical box halves in contact with each other, about contact rims. Opposing recesses are provided at the interfaces of the contact rims to form passage openings when the halves are closed. According to the invention the passage openings are of sufficient sized so that the usual elements of the measuring instrument assembly extending through the protection box walls fit with excess space. The passage openings are tightly sealed by an inserted molded plug made of an elastic foam material. Passages for the parts of the measuring instrument assembly entering or exiting the protection box can be installed at the installation site in such manner that said parts are tightly enclosed under tension by the elastic synthetic material of the molded plug. Universal application of the protection box and proper functioning as well as easy handling are achieved.
