<p>The measuring device (2) has an absorbent (8) to absorb aerosol-air mixture from a work chamber (4) of a work machine and feeds to a sensor unit with an optical emitter (15) and a receiver (17). The absorbent is designed as compressed air jet pump with a compressed air inlet (26), a compressed air nozzle (32), a funnel-shaped pressure discharge channel (30) and a low pressure area (10). The optical sensor unit has an optical passage between optical emitter and optical receiver, and is aligned vertical to the outlet direction of the compressed air nozzle and leads to the low pressure area. An independent claim is included for a method for detecting measured values of gases or of an aerosol in a working chamber of a working machine.</p> |
