A Continuously Operated Gas Analyser Abstract The gas analyser comprises a detector (3), which is dependent upon the mass flow, with a suction device (4) at the detector output. The detector output is connected to a vacuum regulating circuit (6) which maintains the vacuum constant, generated by the suction device (4), at the detector output in relation to the atmospheric pressure. The detector (3) is preceded by a choke (2) in the pipe-line for the gas to be measured. A second choke (11) is connected in parallel, by way of by-pass, to the series arrangement of the first choke (2) and the detector (3). A further (third) choke (1) is connected in advance of the common gas inlet (12, 13). A second vacuum regulating circuit (14) is connected to the common connection point and maintains the pressure constant, prevailing at said connection point, in relation to the atmospheric pressure. The two vacuum regulating circuits (6, 14) each comprise a piezoelectric pressure sensor (18a, 18b), a PI-controller (20a, 20b) and an electropneumatic control element (21a, 21b).
