Abstract

Un sensore di pressione per comando di impianti di condizionamento e simili comprendente un corpo per alloggiare due gruppi ad intervento meccanico a scatto ed una parete di separazione di fluidi in cui il corpo ha un foro centrale passante per comunicare con l'impianto di condizionamento. Inoltre il corpo comprende anche una unità elettronica comandata da una membrana elastica recante un trasduttore connesso ad un circuito microelettronico.
