RADIATION THERMOMETER FOR WIRE

摘要

PURPOSE:To compensate the sensitivity irregularity of a light receiving element material in the axial and photometric directions of a wire material by shielding a portion of the field of a rectangular target. CONSTITUTION:There is fixed to a end side wall 14a of a rectangular mask 14 by means of a stop screw 22 a shielding plate 20 of phosphor bronze which has its one end face formed into an inverted L-shaped stay 20a. There is provided at the opposite side of the stop screw 22 an adjusting screw 24 which is fastened into the end side wall 14a of the rectangular mask 14. By changing the insertion depth of the screw 24, the shielding position and range of the view of the rectangular target by the shielding plate 20 are changed.
