Apparatus for transferring mechanical motions representing measured quantities

摘要

There is disclosed herein an apparatus for converting mechanical quantities, such as mechanical force, into an electrical signal by a mechanism which minimizes explosion possibilities. The mechanism includes a transmission rod which passes through a circular passageway in a wall that separates the mechanical and electrical sections of the apparatus, the transmission rod being tiltable within the passageway to transmit mechanical movement to the electrical section of the apparatus.
