Abstract RU 2117937 C1

FIELD: measurement of low values of dew point under high pressures. SUBSTANCE: hygrometer incorporates measurement chamber, light source, photodetector, cooler and temperature-sensitive element. Measurement chamber has cylindrical ducts made in symmetry. Surfaces of ducts are condensation surfaces. Axes of ducts present generating lines of surfaces of hyperboloid of two sheets. Collection screen is placed in front of photodetector. EFFECT: given hygrometer allows dew point to be measured with reduced amount of analyzed gas. 1 dwg
