Abstract: A sampling system for separating gaseous samples from a gas stream containing particulate matter and transporting the gaseous samples to a location outside of the flowing gas stream comprises an inertial filter mounted on the end of a hollow probe, the inertial filter positioned within the flowing gaseous stream. The inertial filter comprises a filter media mounted within a tube such that a portion of the particulate-containing gaseous steam flows through an annular space between the filter media and the tube wall, the gas to be sampled passes through the filter media into an inner space and the filtered gas is then delivered through the hollow probe to analytical devices external to the space containing the flowing gas stream, such as a flue stack.

Abstract: The invention relates to a waste gas measuring device comprising a gas sampling device, a gas analysis device and at least one gas guiding member through which the waste gas can be guided along a gas path from the gas sampling device to the gas analysis device.

Abstract: The invention relates to an analysis gas-cooling device with a circuit for a cooling agent, which flows through a compressor, a liquefier, and an evaporator.

Abstract: According to the present invention an oxygen measuring cell (10) is suggested comprising inlet conduit means (28) and outlet conduit means (30) for gas to be analyzed, further comprising two nitrogen-filled gas balloons (60, 62) arranged at respective ends of a dumbbell (58) which is secured, in its middle section, to a torsion part (54) arranged in transverse relationship to said dumbbell (58) for forming a torsion balance, further comprising magnet means for producing an inhomogeneous magnetic field in the region of said torsion balance, and comprising a measuring chamber (22) surrounding said torsion balance, said measuring chamber being, at least partially, of rotationally symmetric shape, said torsion part (54) extending along the longitudinal axis of said measuring chamber (22).

Abstract: A process line conveying processed fluid under substantial pressure and having a branched connector is connected to the process duct of a measuring instrument through a pressure duct having first and second coupling sleeves fastened to the branched connector and the process duct, respectively. A first adapter piece is fitted and fixed within an end of the first sleeve and a second adapter piece is fitted and fixed within an end of the second sleeve, the adapter pieces having a diameter equal to the diameter of the pressure duct, and first and second releasable clamping sockets are disposed between the first and second adapter pieces and the respective opposite ends of the pressure duct.
