Methode's team designed a sensor switch that uses field-effect technology to monitor fluid levels within residential sump and sewage pits. LevelGuard® is a software free, solid state pump switch that turns your sump or sewage pump on and off. The field-effect of a touch cell detects any conductive mass (water) entering or changing the field and activates the pump evacuating the water from the pit. The field-effect sensor emanates through any dielectric substrate such as glass or plastic. Field-effect touch cells can be easily integrated in any kind of application and are the perfect sensor solution for fluid level control.
