DIFFERENTIAL BAROGRAPH WITH PHOTOGRAPHIC RE CORDING OF THE READINGS,
Abstract
An instrument intended for continuous recording of chan atmospheric pressure is described. It is called a differential barograph. Its sensitivity is 10-12 times higher than the sensi tivity of a mercury barometer. There are no metal springs in the instrument; therefore its readings are free from the distorting effect of hysteresis and elastic aftereffect. The instru ment was initially intended for observations of barometric leveling at field stations; later it began to be used for control observations when studying certain geophysical phenomena. In par ticular, it was used at the Institute as a con trol instrument when studying terrestial tides. The barograph can also be used in those cases where increased demands are made on the accuracy of recording atmospheric pressure. (Author)
