device for the wireless measurement of process parameters in the thermal treatment of workpieces in an autoclave for the heat treatment of materials

摘要

For in material heat treatment autoclave(1)In workpiece is heat-treated in the case where to process data carry out radio detection device,It is characterized in that workpiece and/or workpiece holding frame(6)At least one passive sensor arrangement(2),Wherein,Sensor device(2)A change at least one physical characteristic of sensor temperature and/or include such mode in the case where pressure change,I.e.,In autoclave(1)The first antenna of middle at least one electromagnetic wave free space for transmitting and receiving of setting(3),Autoclave(1)In first antenna(3)Via autoclave(1)Cable feedthrough with as transmitter/receiver(7)The harness electromagnetism swash of component connects,The transmitter/receiver(7)With autoclave(1)External data processing system(5),The sensor device(2)It is the second antenna for Fa She/reception free space electromagnetic wave(4),Wherein,By means of change of reflection sensor and/or the component as transponder the second antenna with electromagnetic wave(4)It is coupled to the sensor,And the areas E of at least autoclave inner-wall(1): absorber and/or absorbed layer electromagnetic wave propagation.
