Condenser plate assembly

摘要: A sensor and alarm device for sensing the level of a liquid in non-conductive container, including condenser plate assembly to be secured container capacitive coupling its contents further an electronic bridge circuit connectable said operative actuate when sensed is reached by liquid, comprising flexible web having adhesive on one side electrically conductive plates fixed other web, being folded along plural transverse lines so that portion overlap with another adjacent thereof form connector tab, housing containing circuit, supporting multiple electrical contacts mate grip tab secure thereon, providing low mutual capacity between circuit.
