These LS-52100 Series Level Switch units solve the problem of point level sensing in tanks with inaccessible tops or bottoms, or at intermediate locations in larger tanks. Operation is positive and dependable. The float pivots with changing liquid level, displacing a shuttle which magnetically actuates a hermetically sealed switch within the unit. Installation is through the tank side at the detection point. Rugged, all-stainless steel unit offers broad chemical compatibility at temperatures to 300°F (149°C).
