LNC-NS129-120产品概述
In Models NS129 and NS139 (Pump Down) the output relay is de-energized until the liquid reaches the high probe. When liquid touches the high probe, the output relay is activated until the level drops below the low probe. If the tank is non-conductive, a third (common) probe must be installed at a level where it will always be submerged.
