Abstract

Inventia se refera la un dispozitiv de protectie a instalatiilor de oxigen si alte instalatii cu gaze lichefiate împotriva exploziilor. Dispozitivul, conform inventiei, este constituit din doi traductori de temperatura a caror tensiuni sînt amplificate de doua amplificatoare obtinîndu-se doua tensiuni care se aplica la intrarea unui amoplificator diferential, realizîndu-se o diferenta de tensiune ve se aplica în continuare pe un comparator care compara tensiunea diferentiala si tensiune de referinta si care, în momentul egalitatii lor, se creeaza o tensiune care se aplica la un bloc electric de semnalizare si reglaj, care la rîndul sau comanda închiderea unui electrovalve concomitent cu declansarea unui sistem de avertizare sonora si acustica.
