ELS Float Switch

Product Description

The WIKA ELS float switch is a unique float switch due to its functioning. In an external chamber (bypass chamber), afloat with a permanent magnet moves on a guide tube in relation to the liquid level, following the principle of communicating vessels. Within the guide, the tube is fitted a reed contact (inert gas contact), which is energised, through the non-magnetic walls of the float and guide tube, by the approach of the float magnet. By using a magnet and reed contact, the switching operation is non-contact, free from wear, and needs no power supply.

The connections of the level switch are potential-free. The switching functions always refer to a rising liquid level. The level switch is simple to mount and maintenance-free, so the costs of mounting, commissioning and operation are low.
