Dual Liquid Level Sensor – 200 mm

Description

Made of stainless steel and equipped with two floats, one for the minimum level and one for the maximum level, this float switch is used to detect the level of a liquid inside a tank and can activate a pump, a warning light, an alarm, or other device. It has four wires, two for each float.

Operation is very simple: assuming vertical mounting with the wires facing upward (e.g., on a tank lid, etc.), when the liquid level does not reach the lower float (minimum level), the corresponding contact is closed. As soon as the liquid lifts the float, that contact opens.
When the liquid reaches the upper float and lifts it (maximum level), the contact of the latter opens.

Technical specifications

• Switching system: Reed in the body and magnet in the floats
