ABSTRACT:
A remote pressure or vacuum sensing device including a housing having first and second chambers separated by an internal wall, the first chamber being in fluid communication with a pressurized or vacuum environment to be monitored. An activator assembly is carried within the first chamber for axial movement therein between a terminal position and other positions in response to fluid communication of pressure or vacuum conditions of the monitored environment to a portion of said activator assembly. An activatable assembly is carried within the said second chamber for activation upon movement of the activator assembly from its terminal portion to other positions to provide signals for indicating pressure changes in the monitored environment.
