Description

(54) ДЕТЕКТОР ПО ТЕПЛОПРОВОДНОСТИ(54) THERMAL CONDUCTIVITY DETECTOR

тельность. Сравнительные испытани  показали , что чувствительность предложенного детектора в 2,5 раза выше чувствительности детектора с двум  чувствительными элементами , при этом другие параметры детектора , в частности посто нна  времени и степень размыти , сигнала, остались без изменений .tolerance. Comparative tests have shown that the sensitivity of the proposed detector is 2.5 times higher than the sensitivity of the detector with two sensitive elements, while other detector parameters, in particular, the time constant and the degree of smearing of the signal, remained unchanged.
