の液面感知装置。[Claims for Utility Model Registration] (1) A float that receives buoyancy from a liquid, a magnet for generating magnetic force, an adsorbent made of a magnetic material disposed opposite to the magnet, and an outer periphery of the float. A hollow tubular guide member made of a non-magnetic material that is slidably inserted into a surface, and a switch that is disposed within the guide member and opens and closes a contact by the magnetic force, and the magnet is attached to the float. and an adsorbent are integrally fixed to form a float structure, and a buoyancy force acting on the float structure;
A liquid level sensing device comprising means for expanding and adjusting the opening/closing width of the switch by balancing a force obtained by adding the weight of the float structure to the holding force of the magnet acting on the attracting body. (2) The liquid level sensing device according to claim 1, wherein the magnet has a magnetic force for opening and closing the switch and a magnetic force for holding the float via the adsorbent.
