Abstract

PURPOSE:To prevent the erroneous operation of a device, by a method wherein an expansion bag is detected quantitatively and continuously, and expiration is sampled as a exhaust gas amount is continuously controlled. CONSTITUTION:An expansion of a bag 2 resulting from the input of expiration is detected by a potentiometer 7, and through the comparison of the result with a set value, opening and closing of a motor-operated 3-way distribution valve 5 is controlled through the working of a power-operated controller 8. The bellows type bag 2 and a potentiometer 7 conduct a circular movement centering around the potentiometer 7 acting as a rotary shaft in a manner that one end of the bellows is fixed and the other end is free, and the expansion amount of the bag 2 is detected as a change in resistance through the rotation of the potentiometer 7. This constitution permits the continuous collecting of a sample through the control of an opening degree of the motor-operated 3-way valve and prevents the erroneous operation of a device.
