Abstract

medidor com motor de passo trata-se de um medidor que inclui um alojamento e uma conexão com uma entrada, uma via de fluxo interna e uma saída. um sensor comunica-se fluidamente com a via de fluxo interna e mede uma característica de um fluido nesta. uma unidade de controle comunica-se eletricamente com o sensor de pressão, recebe uma saída do sensor de pressão e gera um comando com base nesta. um motor de passo possui um eixo de rotor com uma agulha indicadora conectada operacionalmente a ele e comunica-se eletricamente com a unidade de controle. uma fonte de alimentação comunica-se eletricamente com o sensor de pressão, o motor e a unidade de controle para alimentar energia a eles. a unidade de controle transmite o comando ao motor de passo, que, por sua vez, recebe o comando advindo a unidade de controle e aciona o eixo de rotor de acordo com ele, indicando assim a característica detectada por meio de agulha.
