Abstract

"CéLULA DE CARGA". O presente resumo refere-se a uma patente de invenção para célula de carga, pertencente ao campo dos dispositivos acionados por pressão, que foi desenvolvida para atender à função a que se destina e ter construção simples compreendida: por diafragma elástico de tipo coxim (1), que fica com uma superfície sujeita à pressão 'P' a ser monitorada; por corpo, externo, fixo (10) dotado de meios externos (11) para assentamento no local de uso (50); de passagem interna (12); de extremidade (13), na qual fica assentado o diafragma (1) e de rosca interna (14); por corpo interno, móvel (20) dotado do, passagem interna (21); de batente extremo (22), que fica adjacente ao diafragma (1) e limitador do curso deste; de rosca externa (23) enroscada na rosca interna (14) do corpo externo, fixo (10); por micro-chave elétrica (30), assentada na extremidade do corpo móvel (20) oposta ao batente (22) e cujo botão (31) é acionado pelo diafragma (1); e por tampa (40) de fixação da micro-chave (30) no corpo móvel (20)."LOAD CELL". This summary relates to a load cell patent belonging to the field of pressure actuated devices which has been developed to fulfill its intended purpose and to be of simple construction comprising: cushion type (1) elastic diaphragm ), which has a surface subject to pressure 'P' to be monitored; external fixed body (10) provided with external means (11) for seating at the place of use (50); internal passageway (12); end (13) on which the diaphragm (1) is seated and internal thread (14); by movable inner body (20) provided with the inner passage (21); end stop (22), adjacent to the diaphragm (1) and limiting its travel; outer thread (23) threaded into the inner thread (14) of the outer body, fixed (10); by an electric micro-key (30), seated on the end of the movable body (20) opposite the stop (22) and whose button (31) is actuated by the diaphragm (1); and by cap (40) securing the micro-key (30) to the movable body (20).
