E 218.3/25

Other/spare parts

Function description: As the tank level falls or rises, a float with a built-in magnet moves along the guide tube. When the magnet reaches the level of the reed switch, the contacts are switched on and the electrical circuit of the connected device (signal light, horn, motor contactor, etc.) is connected. The upper third contact, always located approximately 60 mm above the maximum level switch, is used to signal the danger of overfilling the tank. The position of the float in the limit switch positions is secured by adjustable stops to keep the contacts permanently closed.

Float control with opening contacts: the E 218.3/xx/R type is identical in material, design and function to the E 218.3/xx type. The only difference is the higher degree of protection - IP 55 according to EN 60529 and the reversed function of the reed contacts. The higher degree of protection is achieved by the use of an "O" ring inserted in the socket of the head under the cover.

The reversed function of the reed contacts is such that if the magnet reaches the contact, it will be disconnected (circuit break).
