<p>A device for identification of a filter holder (4, 13) of an espresso coffee machine, comprising a support (3, 17, 18) on which the filter holder to be identified is removably placed, at least one thermopile radiation sensor (6, 6a) having a plurality of heat radiation-sensitive elements, an optical apparatus (8, 8a) that focuses radiations on said sensitive elements and circuit means, which receive electric signals transmitted by said sensitive elements and process a corresponding output signal. Said radiation sensor (6, 6a) is placed, relative to the support (3, 17, 18) for the filter holder to be identified, such that at least one portion thereof (10, 11, 15), when it is placed on the support, falls within the field of view (9, 9a) of the optical apparatus (8, 8a) of said sensor, such that said circuit means can determine a signal representative of the radiations of the filter holder portion detected by said optical apparatus of the sensor. According to the invention, the filter holder portion that is identified by the radiation sensor is a beverage dispensing spout portion of the filter holder.</p> |
