Gems Sensors Series Level Switch
Side Mounting, Large Size, Alloy Switches Solve the Problem of Inaccessible Tank Tops & Bottoms
Quick Specs...
Overview / Design Principle:
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 level, 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 to 900 PSIG and temperatures to 300°F. Explosion-proof models available.
