Side Mounting Float Switch FineTek C€ <g> Innovation • Quality • Sharing

WORKING PRINCIPLE The reed switch relies on two basic scientific principles namely: buoyancy and magnetism. Buoyancy causes the float (which contains a magnet) to rise with the liquid and magnetism helps open and close the switch. A change in liquid levels raises or lowers the float up or down. The end of the pivot arm (non float side) contains a permanent magnet that can repel the switch magnet (inside the stationary ‘stem’ of the entire structure). The side mounted float level sensor (FF series) are manufactured specifically for horizontal mounting on tanks or vessels. They work well as high...

3. Flange 6. Reed Switch The length of the nozzle has to be comply with the pipe diameter. If the length of nozzle is too long It will affect the switching movement. The suggested maximum length of the nozzle is listed as below chart: (Unit: mm) ©: Float dia is larger than fhe nozzle dia so sensor cannot be insert. ◎: Nozzle

1. SUS304/SUS316 materials are not available for corrosive application. 2. The cable duct(s) must face downward to prevent moisture seeping in. 3. The float and extension rod must be inserted into the bin completely. 4. Check the liquid's S.G. level before installation. 5. The mounting hole must be larger than the external diameter of the float. (Please refer to p2) 6. Don't mount the devices near the bin's inlet or outlet.
