DEVICE AND METHOD FOR DETERMINING THE WEIGHT OF PHARMACEUTICAL PRODUCTS BY MEANS OF AN X-RAY SOURCE

摘要

The invention relates to a device (10; 10a) for determining the weight of pharmaceutical products (1), in particular of hard gelatin capsules (3; 3a) filled with a pharmaceutical (2), by means of an X-ray source (28), wherein the X-ray source (28) generates a radiation cone (27; 36, 37) which passes through at least one pharmaceutical product (1), and wherein a sensor element (30; 30a) detects the radiation of the irradiated pharmaceutical product (1) and supplies an evaluation device (32). According to the invention, a reference object (35; 35a; 35b) is arranged in the beam path of the radiation cone (27; 36, 37), wherein the radiation of the X-rayed reference object (35; 35a; 35b) is detected by means of the sensor element (30; 30a; 30b) and is supplied to the evaluation device (32), and wherein the pharmaceutical product (1) and the reference object (35; 35a; 35b) are positioned in relation to the radiation cone (27; 36, 37) in an arrangement in which they do not overlap each other in the radiation cone (27; 36, 37).
