Description of the Float switch
With its compact design, the model HLS-M float switch for horizontal installation in miniature design is ideally suited for use in small tanks, for indicating minimum/maximum levels.
The float is attached to a supported, swivelling lever and moves with the level of the medium being measured. By means of a permanent magnet, when a preset switch point is reached, a reed contact (inert gas contact) is actuated.
By using a magnet and reed contact the switching operation is non-contact, free from wear and needs no power supply. The contacts are potential-free.
The switching function refers to a rising liquid level: Standard use as normally open contact (can be used as normally closed contact by a 180° rotation).
The float switch is simple to mount and maintenance-free, so the costs of mounting, commissioning and operation are low.
