Abstract

Inventia se refera la un dispozitiv de calibrare a unui monitor optic, utilizat la urmarirea concentratiilor de praf în curenti de gaze, si consta în utilizarea unui fotoreceptor de calibrare care este introdus într-o bucla de reglaj automat al fluxului luminos emis de o lampa în functie de prafuirea elementelor optice si de uzura lampii, trecerea pe calibrare realizându-se pur electronic. în acest mod se înlatura elementele în miscare la trecerea pe calibrare si, în acelasi timp, se realizeazaocalibrare dinamica, eliminându-se automat eventuale surse de erori în procesul de masurare.The invention relates to a device for calibrating an optical monitor used to track dust concentrations in gas streams and consists of using a calibration photoreceptor which is inserted into an automatic control loop of the light output emitted by a lamp in depending on the dusting of the optical elements and the lamp wear, the passage on the calibration is carried out electronically. In this way the moving elements are removed from the calibration passage and, at the same time, the dynamic calibration is made, automatically eliminating the possible sources of errors in the measurement process.
