Abstract: A control cabinet for an exhaust gas measuring facility. The control cabinet includes a cabinet body with measuring appliances for analyzing at least one sample gas. The cabinet body includes two side walls, a bottom, a cover, a first rear wall, a second rear wall, a front side, and a channel which is arranged between the first rear wall and the second rear wall. The channel is dissipates heat. A door opens and closes the front side of the cabinet body.

Abstract: A system for taking exhaust gas samples from internal combustion engines includes an exhaust gas duct comprising an outflow cross section and an exhaust gas inlet. The exhaust gas duct communicates with an exhaust gas source via the exhaust gas inlet. An air duct takes in ambient air via a filter. The outflow cross section is concentric in the air duct. A mixing zone is arranged downstream of the outflow cross section. A dilution tunnel has an exhaust gas/air mixture flow therethrough. An annular orifice is arranged downstream of the outflow cross section in the dilution tunnel. A flow deflection device is arranged upstream of the annular orifice and downstream of the outflow cross section. The flow deflection device deflects the exhaust gas/air mixture so that it departs from a center axis of the dilution tunnel immediately downstream of the flow deflection device in an axially symmetrical manner.

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 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.

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.
