Abstract: An air curtain device and method are disclosed for realizing an air curtain with measuring a temperature profile. The air curtain device includes: a housing with air displacer; at least one air inlet for supplying air to the housing; at least one outflow opening for achieving the air curtain; a sensor configured for measuring a temperature profile over a length extending through the air curtain in a substantial horizontal direction and substantially perpendicular to the air curtain; and a controller with connector configured for connecting with the sensor, the controller configured for adjusting the air curtain based on differences between the measured temperature profile and a reference profile.
