FIELD: machine building.
SUBSTANCE: device includes recognition unit (32) provided for recognition of presence of at least one type of material at least in one specified zone (34) of a technological machine. Recognition is performed by means of a spectrum emission analysis. Recognition unit (32) includes sensor assembly (44) at least with one sensitivity range for recording of emission in the range of wave length, which is situated in an electromagnetic wave spectrum. Device includes transmission device (42; 64) provided for transmission of emission, and analysis device (58) having the possibility of determining the presence at least of one type of material at least in one specified zone of the technological machine based on the emission recorded by sensor assembly (44). At that, analysis device (58) is functionally related to transmission device (42).
EFFECT: improving recognition reliability of a working situation of a technological machine.
