Abstract: A condensate discharge system for an exhaust gas measuring device. The condensate discharge system includes a condensate separator in which a positive pressure prevails, an outflow line in which atmospheric pressure prevails, a connecting line, and an intermediate reservoir in which the positive pressure prevails. The intermediate reservoir is arranged between the condensate separator and the outflow line and is directly connected to the condensate separator via the connecting line. The intermediate reservoir includes a float valve via which a condensate is dischargeable into the outflow line.

Abstract: A condensate separator for an exhaust gas measuring system. The condensate separator includes a housing with condensate discharge opening, an inlet opening arranged in the housing, a cooled inlet line which introduces a fluid into the housing, and a gas outlet port with a gas entrance and a gas exit. The cooled inlet line opens into the inlet opening. The gas outlet port opens into a gas outlet line. A cross-sectional area of the gas entrance of the gas outlet port is larger than a cross-sectional area of the gas exit of the gas outlet port.

Abstract: A switch cabinet for an exhaust-gas measurement installation includes a cabinet body with two side walls, a ceiling, a floor, a front side and a back wall, a door to close the front side, a measurement gas distributor arranged in the cabinet body with an outlet, a coupling element fastened to the measurement gas distributor to form the outlet, at least one measuring device arranged in the cabinet body with an inlet, and a coupling element fastened to the at least one measuring device to form the inlet. The inlet is connected to the outlet to provide a gas-tight connection. The measurement gas distributor moves relative to the cabinet body so that the coupling element fastened to the measurement gas distributor and forming the outlet can be connected by insertion to the coupling element fastened to the at least one measuring device and forming the inlet.

Abstract: A gas feed unit for an exhaust gas analysis unit includes a measurement unit for analysing a sample gas, a connection line arranged so that a calibration gas line, a purge gas line, and a sample gas line opens thereinto and which fluidically connects to the measurement unit, a shut-off valve arranged in each of the calibration gas line, the purge gas line, and the sample gas line, a pump which delivers the sample gas from an exhaust gas source, an outflow line with an outflow nozzle and a shut-off valve, and an outflow nozzle arranged at an end of the connection line opposite to the measurement unit. The outflow line branches off from the connection line. The sample gas line is arranged to open into the connection line between the measurement unit, the calibration gas line, and the purge gas line.

Abstract: A control cabinet arrangement for an exhaust gas measurement device. The control cabinet arrangement includes a first control cabinet which delimits a first interior space and a second control cabinet which delimits a second interior space. A first heat-generating component of the exhaust emission measurement device is arranged in the first interior space. A second component of the exhaust emission measurement device is arranged in the second interior space. At least one fluidic connection connects the first interior space and the second interior space. The second component is heatable by an air flow flowing between the first interior space and the second interior space.
