摘要： An electrically resistive fluid level sensor and system for sensing fluid levels in a container, for example washing machine basins, and for closing a supply of fluid to the container when the fluid level in the container reaches a specified level. The system includes generally fluid level resistive element portions disposed in the container and electrically connectable by fluid therein, and an input signal source, electrically coupled to the fluid level resistive element portions, whereby an output signal across the fluid level resistive element portions is proportional to the fluid level. Temperature resistive element portions are preferably disposed in the container and connected in series between the input signal source and the fluid level resistive element portions to substantially cancel any thermal effects on fluid level sensing and control. The fluid level resistive element portions are electrically coupled to a signal input of a comparator circuit, whereby an output signal of the comparator circuit closes the supply fluid to the container when the fluid therein reaches a specified level.

摘要： The present disclosure relates to a restriction indicator for an air cleaner system of an internal combustion engine. The restriction indicator includes a housing divided into first and second chambers by a diaphragm. A signal member is connected to the diaphragm. The signal member is moveable along an axis between a reset position and a first indicator position, and defines an axial opening within which a first retaining shoulder is located. A guide member is provided for guiding the signal member as the signal member is moved between the reset position and the first axial position. A retaining member is provided for retaining the signal member in the first indicator position. The retaining member extends within the axial opening of the signal member and includes at least two fingers that project radially outward from the axis. The fingers are configured to engage the first retaining shoulder to retain the signal member in the first indicator position. The restriction indicator further includes a reset button for deflecting the fingers radially inward to disengage the fingers from the first retaining shoulder thereby allowing the signal member to be returned to the reset position. The reset button includes a portion that extends within the axial opening of the signal member between the retaining member and the signal member.
