Description

Single Stage Switch T20 units are simple, reliable float switches, designed for top mounting into tanks or vessels. T20 units utilize a single switch mechanism and float. It can be used for virtually any type of open or closed process or storage vessel, with either threaded or flanged type mounting, and actuating depths of up to 48 inches (1219 mm). All float operated liquid level controls operate on the basic buoyancy principle which states "the buoyancy force action on an object is equal to the mass of liquid displaced by the object." As a result, floats ride on the liquid surface partially submerged and move the same distance the liquid level moves. Because of this, they are normally used for narrow level differential applications such as high level alarm or low level alarm. Float diameters of 3" × 5", 4" and 4½" available Tank connections available in 1" NPT, cast iron, forged, or stainless steel flanges Choice of switch mechanism: ◦ Dry contact ◦ Hermetically sealed ◦ Pneumatic Choice of switch enclosure: ◦ NEMA 1 carbon steel for pneumatics ◦ TYPE 4X/7/9 Class I, Div. 1, Groups C & D, polymer coated aluminum ◦ TYPE 4X/7/9 Class I, Div. 1, Group B, polymer coated aluminum OPTIONS NACE ATEX approved housing Housing heater Float guide cage Tropicalized switch mechanism Special flange face finishes Submersible housing Elevated temperature
