DEVICE FOR AUTOMATIC SAMPLING Russian patent published in 2003 - IPC

FIELD: equipment for remote automatic sampling in ground atmospheric layer. SUBSTANCE: invention can also be used to evaluate content of impurities in air and dynamics of their propagation. Target of invention lies in provision for automatic taking air samples at various altitudes which enables authenticity of evaluation of condition in ground atmospheric air and operational reliability of device to be raised. Device for automatic sampling is made up of altitude column, endless tape, samplers and system of liquid draining communicating through shut-off and control equipment with samplers and tankaccumulator. Pistons with floats installed in samplers go down while liquid is drained through system of liquid draining to tank-accumulator. With this air is sucked into spaces located pistons through conical bell mouths. In extreme low position of piston in body bell mouth is shut off by end-piece. EFFECT: raised authenticity of evaluation of ground atmospheric air and operational reliability of device. 1 cl, 3 dwg
