The float switches 7030 belongs to a generation of float switches where the mercury switches have been replaced with up-to-date environment friendly materials.Because float switches are often used inenvironmental engineering systems such as pumping stations and sewage plants, it is very important that the switches do not contain mercury.When used for control or alarm in pumping stations, the float switches can be easily damaged during the replacement of pump and other machinery.
Special features:
• Float switches without mercury
• The float switch is made of polypropylene, an environment friendly and strong material
• Electro-mechanical contact system
• The electro mechanical contact system with a voltage-free switch can withstand loads up to 16A allowing a motor starter to be connected directly
Function:
The float switches 7030 are supplied with an electro-mechanical contact system.In the float switch with electromechanical system a hermetically sealed micro-switch is built in, which is activated by a moving weight. The weight activates the micro-switch, when the float switch 7030 changes its position in the water. As accessories a counterweight can be delivered, the coun-terweight ensures that the 7030 is always drowned, and it makes the bend of the cable less sharp.
