A submersible pump is used as an instrument to supply construction sites and facilities with water. However, the operation with no water to pump shortens the product's life and leads to mechanical noise. We developed a new model line mounted with capacitance sensor which detects water accurately with built-in operational function which detects water level automatically, enabling operation only when it detects water to pump. It reliably detects the water level by capacitance and its microcomputer control responds properly to such disturbance as dirt and adhesion of waterdrops, leading to reduction of malfunction. It also provides not only sensor enabling easy alteration of water level to be controlled, but also function for optimum operation which shortens the period of time with no water to pump and, thereby, reduces operation frequency. It's a new product which leads the market by achieving energy saving.

水中ポンプは工事現場や設備に水を運ぶ機器として使用されますが、水の無い渇水運転は、製品寿命を縮め、騒音を発生させます。当社では、水があるときだけ運転する水位自動運転機能をポンプ自体に内蔵し、水の検知を正確に行うための静電容量式センサーを搭載した製品を開発しました。静電容量で水位を確実に見極め、マイコン制御で汚れや水滴付着など外乱にも対応し、誤作動を減らします。また、簡単に制御水位を変更できるセンサーや、渇水時間を短くし始動頻度を少なくする最適運転行う機能があり、省エネを実現し業界をリードする商品です。
