Field effect dector cells
*Mirus dector cells are composed of an active device and an electrode surrounded by a second electrode.The applied circuit creates an electric field around the cell. When a dielectric material (such as bilge water) interrupts the field the active device responds by outputting a signal. In the case of the ULTIMA switch, this signal is used to automatically control your bilge pump.
