Abstract

Inventia se refera la un dispozitiv electronic de semnalizare la nivelmetrul cu futun format din doua sonde, introduse prin dopuri de reglaj prin cele doua tuburi de sticla de la extremitatile furtunului nivelmetrului sondele fiind conectate prin conductoare la aparatul care contine un prim tranzistor în montaj colector comun conectat, în continuare cu al doilea tranzistor în montaj emitor comun în colectorul caruia este plasat un bloc de semnalizare a egalitatii nivelului celor doua sonde montajul fiind alimentat de la o baterie prin întrerupator.The invention relates to an electronic signaling device at the level of a futon consisting of two probes, inserted through the adjusting plugs through the two glass tubes at the ends of the level meter hose, the probes being connected by conductors to the apparatus containing a first transistor in common collector assembly further connected to the second common emitter transistor in the collector, which is placed on a level signaling block of the two probes, the assembly being fed from a battery by a switch.
