Cable Float Level Switch is a control device for filling and discharging pumps, motor, and magnetic valves. It is also an alarm device at certain pre-determined surface levels. It is suitable for use in non-flammable liquids at 250 volts. In dangerous environments (e.g. wells and pumping stations) we recommend 24 V voltage. In potentially explosive atmospheres (e.g. oil tanks) the Switch can be used in conjunction with (Ex) i-isolator switch units. Due to its large float casing, the float Switch has a buoyancy which guarantees smooth, trouble-free operation under all conditions. The switch has the double chamber and a final remolding finish to make it absolutely hermetic.
