LS-2050 Series Level Switch

Brand: Gems Sensors, Inc

These LS-2050 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 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 psig: 900 (kPa: 6,200, bar: 62) and temperatures up to 149° C (300° F).

Explosion-proof models are available.
