What is Electric Field Sensor Technology?
The circuit within the Supersub Smart 650 creates an electric field which passes through one side of the rear housing of the pump. The field exists above the rougher textured pad allowing the user to identify where to put their thumb to test if the pump has been correctly installed. If a dielectric material, such as a human thumb or water within the bilge of a boat covers the area denoted by the rough texture, the circuitry registers the disturbance in the electric field and if covered for 2 seconds or more activates the pump’s motor. When the bilge water (dielectric material) has been removed or gone below the level of the textured pad, the electric field is no longer experiencing a disturbance. A timer allows the pump to run for a further 15 seconds in order to remove water below the sensor and water currently in the pipe-work, before turning off.
