prikazana jeftina verzija detektora nivoa vode. Radi na istom principu kao i LM1830, ali je cjenovno puno jeftiniji (mada ima više dijelova). Aktivni izlazni novo je 0V. Verziju možete pojeftiniti izbacivanjem 74HC14, dioda BA157 i izlaznog filtera 100K-1uF. Time dobivate nezaštićen ulazni krug, nefiltrirani izlazni krug te aktivni visoki izlazni nivo. U području kada je detektirani napon blizak pragu detekcije, vanjske smetnje će dodatno modulirati izlazni napon te o tome treba voditi računa. Ako je izlaz namjenjen samo signalizaciji tada treperenje u rubnom području i nije toliko važno. Međutim, ako želite pouzdan signal, tada preporučujemo upotrebu filtra i schmitt triger sklopa (npr. 74HC14) na izlazu LM567.</div> <div>      Sklop je provjeren i radi odlično. Dužina vodova do elektroda nije kritična i može biti i 10 metara (parica ili niskokapacitivni koaksialac). Za elektrode upotrebite nehrđajući materijal (procrom).</div> <bR> </td> </tr></table></body>
