Abstract

Inventia se refera la un dispozitiv electronic de protectie realizat cu un amplificator comparator, la a carui intrare neinversoare a aplicat semnalul de la traductor printr-o punte redresoare, un condensator de filtraj si un potentiometru, la a carei intrare inversoare e aplicata tensiunea de referinta printr-un potentiometru de la care e comandat un tiristor cu rol de comutator static, dispozitivul fiind prevazut cu un circuit de semnalizare cu LED. La intrarea amplificatorului comparator mai este conectat colectorul unui tranzistor de automentinere cu emitatorul legat la masa si cu baza conectata, prin circuitul de semnalizare la iesirea amplificatorului.The invention relates to an electronic protection device made with a comparator amplifier whose uninverted input has applied the signal from the transducer via a rectifier bridge, a filter capacitor and a potentiometer at whose inverting input the reference voltage is applied through a potentiometer from which a thyristor is commanded as a static switch, the device being provided with an LED signaling circuit. At the input of the comparator amplifier is also connected the collector of a self-contained transistor with the emitter connected to the table and the connected base through the signal circuit at the output of the amplifier.
