Abstract

Inventia se refera la un dispozitiv electronic de comutare care are la baza controlul continuu al variatiei de curent din circuitul supravegheat, independent de valoarea absoluta sau frecventa acestuia si constituie o perfectionare a inventiei nr. 94489. Dispozitivul contine un comparator specializat (CI) la intrarile caruia se aplica un semnal de masura de c.a. direct de la traductor si un semnal de referinta cu variatie foarte fina obtinut cu ajutorul unui divizor rezistiv special (P2, P4 - brut; P3, P5 - fin), iesirea acestuia fiind conectata la un circuit de comanda si semnalizare (P1, LED V, octocuplorul OC, respectiv la cursorul potentiometrul P5. Dispozitivul electronic prezinta simplitate deosebita, mare sensibilitate, fiabilitate sporita si imunitate ridicata la zgomot.The invention relates to an electronic switching device which is based on the continuous control of the current variation in the monitored circuit, regardless of the absolute value or the frequency thereof, and constitutes an improvement of the invention no. 94489. The device contains a specialized comparator (CI) at the inputs to which a measurement signal of ca. directly from the transducer and a very fine reference signal obtained with a special resistive divider (P2, P4 - P3, P5 - fine), the output of which is connected to a command and signaling circuit (P1, LED V , Octocuplor OC and P5 potentiometer respectively. The electronic device has special simplicity, high sensitivity, increased reliability and high noise immunity.
