Water level sensor for steam humidifier

A water level sensor for a steam humidifier. The water level sensor includes a plurality of conductive probes, where the plurality of conductive probes includes at least one common probe and a plurality of water level probes. Each of the conductive probes are separated from each other conductive probe. The water level sensor further includes a non-conductive overmolding covering at least a portion of each of the conductive probes. The non-conductive overmolding defines a flange configured to seal an opening in a tank of the steam humidifier and an electrical connection point configured to receive an electrical connector for providing electrical connections to each of the conductive probes. A steam humidifier is also disclosed.
