Level Switch – LS-2050(E) Series
These 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 levels, displacing a shuttle which magnetically actuates a hermetically sealed switch within the unit. Installation is through the tank side at the detection point. General purpose materials designed to provide reliable service in oils and water. Ultimate strength: for pressures up to 900 psig (62 bar) and temperatures up to 300°F (149°C). Explosion-proof (CSA/FM approvals only on LS-2050) and intrinsically safe models are available (LS-2050(E) (see ATEX section).
