Description
本発明は前記目的を達成するため、合成樹脂製のケースと、このケースに回動可能に支持されるホルダーと、このホルダーに装着され液面の変動に追従作動するフロートを備えたフロートアームと、前記ホルダーに配設され前記フロートの作動に伴い回動するマグネットと、このマグネットの磁力変化を検出する検出素子とを備えた液面検出装置であって、前記検出素子の出力電圧を安定させる安定化回路を備えているものである。
In order to achieve the above-mentioned object, the present invention provides a case made of synthetic resin, a holder rotatably supported by the case, and a float arm equipped with a float that is attached to the holder and operates to follow the fluctuation of the liquid level. , a rotation to the luma Gunetto disposed in said holder along with the operation of the float, a liquid level detecting apparatus having a detecting element for detecting the magnetic force variation of the magnet, the output voltage before Symbol detection element Is provided with a stabilization circuit for stabilizing the above.
また、前記安定化回路は、コンデンサを含み、前記液面の微変動に対する出力変化を吸収し、検出ノイズの発生を抑制するものである。 The stabilization circuit includes a capacitor and absorbs a change in output due to a slight fluctuation in the liquid level to suppress detection noise .
Claims (2)
The liquid level detection device according to claim 1, wherein the stabilization circuit includes a capacitor, absorbs an output change with respect to a slight fluctuation of the liquid level, and suppresses generation of detection noise .
