Applications ■ For level monitoring and level indication of liquids ■ Level measurement for almost all liquid media ■ Pump and level control ■ Alarm signals ■ Dry-run and overflow protection Special features ■ Lateral installation in the tank ■ Plastic and stainless steel versions ■ Space-saving installation ■ Switch consists of only one component Description With its compact design, the model HLS-M magnetic 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 magnetic float switch is simple to mount and mainte- nance-free, so the costs of mounting, commissioning and operation are low. The following five magnetic float switches are available Level measurement Float switch model Design Installation Electrical connection HLS-M11 Plastic from inside Cable HLS-M12 Plastic from outside Cable HLS-M21 Stainless steel from inside Cable HLS-M22 Stainless steel from outside Cable HLS-M23 Stainless steel from outside Connector |
