Weight: Approximate 0.25kg
Trademark: SJE Rhombus
Transport Package: Box Packing
Origin: China
HS Code: 85365000
Features:

SJE SF2™ float switch is a suspended float switch designed to monitor levels in nonmagnetic tanks (e.g. of stainless steel or plastics). Thanks to the "Flexible Connection Float" technology, it can avoid the interference of the dirties, thus it is very suitable for use in extremely dirty liquids, like septic tank . 

The switch body mounted on the side wall of the tank with the G¾" screw sleeve. A plastic float suspended on the end of a stainless steel cord. Float and cord are inserted in the tank through a G¾" screw plug. As the float rises with the level of the liquid, a permanent magnet inside the float actuates the magnetic switch inside the G¾" screw plug, providing an upper or lower level signal . 

Switching points are provided 10±5 mm below or above the centre line of the G¾" screw plug. A special plastics sealing ring protects the G3/4 screw plug against the thread of the welding sleeve. Thus, only a little sealing material is required when first time installation.


•   No jamming of the freely movable float .
•   Suited for extremely dirty liquids, e.g. septic tank, oily wastewater.
•   Easy installation. Only a little sealing material is required.
•   High precision magnetic switch design.
•   Integral watertight cable (comply with TJ/CL254-2013(V1.0).
•   Registered utility model
•   Tested according to EN 50155 (approved for use on rail vehicles)
