LONGSingle switch widedifferential: 2D, 5D.The two displacer elementsare positioned at any point onthe cable to correspond to theswitching levels required. Whenthe liquid level drops to the lowerdisplacer, a switch is actuatedand starts (or stops) a pump,when the liquid rises to theupper displacer,the switch isagain actuatedto stop (or start)the pump.Two switch 2 narrowdifferentials: 8D, 9D.The displacers are positionedto form two elements ofsimilar lengths, such that twoalarm points may be given.This arrangement is typicalof sump application.Two switch 2 widedifferentials: 3D, 6D.A pump is controlled betweenthe middle and the lowerdisplacers positioned on thecable at the required levels.Should the level rise to theupper displacer, this actuatesthe upper alarmswitch which remainsactuated until the leveldrops to the middle displacer.Alternatively the upperswitch could control asecond pump.NOTE: All models supplied with 10 ft. long SST Cable as Standard.MOUNTING CONNECTIONCODE SIZE CARBON STEEL RATING SST RATING60 3" 150# R.F.
