3 л г -Г -J о где С„ - концентраци  измер емого газа, на которую рассчитан сигнализатор . Монотонное изменение .концентраци  измер емого газа в смесителе обеспечивает значительно большую точность новерки в сравнении с известным способом (в 3- 5 раз) при значительном сокращении времени цовер-ки. Формула изобретени  Способ поверки сигнализаторов взрывоопасных и токсичных газов с датчиками мостового типа путем введени  калибровочных газовых смесей в рабочий объем сигнализатора и регистрации выходного сигнала , отличающийс  тем, что, с целью повышени  точности и ускорени  поверки, камеру датчика сигнализатора заполн ют воздухом, затем вытесн ют постепенно воздух из этой камеры калибровочной смесью и по величине напр жени  па диагонали моста датчика в момент срабатывани  сигнализатора и при полном заполнении камеры калибровочной газовой смесью определ ют погрешность прибора. Источники информации, прин тые во внимание при экспертизе: 1.Ван  Я- Анализаторы газов ,и жидкостей . М., «Энерги , 1970, с. 491. 3 l of r -G —J o where Cn is the concentration of the measured gas for which the alarm device is designed. The monotonous change in the concentration of the measured gas in the mixer ensures significantly greater accuracy of the change in comparison with the known method (3-5 times) with a significant reduction in the sweeping time. DETAILED DESCRIPTION OF THE INVENTION A method for calibrating explosive and toxic gas detectors with bridge-type sensors by introducing calibration gas mixtures into the working volume of the alarm device and recording the output signal, characterized in that, in order to improve the accuracy and accelerate the calibration, the sensor chamber of the alarm indicator is filled with air and then displaced gradually, the air from this chamber with the calibration mixture and the voltage across the diagonal of the sensor bridge at the moment the alarm device is triggered and the camera is fully filled internal gas mixture determined instrumental error.
