Qualiscan QMS-12

Transmission of beta rays The weight monitoring and control system measures the weight continuously, without contact, destruction-free and on moving product. The measurement is based on the attenuation of rays from a radioactive isotope through the substrate located in the measuring gap. This attenuation in intensity is an indication of the weight of the product.

Control of thread density / course density / basis weight The Famacont PMC determines the thread density by means of a non-contacting, optoelectronic or imaging process. With the optoelectronic process individual threads or courses pass the sensor and are projected onto the photocell using a precision optical lens. The resulting frequency is proportional to the thread count. A high-resolution camera is used with the imaging process. The image is analysed with using suitable software (FFT analysis). Both, the thread count in weft and warp direction can be determined here with maximum precision.

Reflexion of infrared light Automatic width measurement on a running product web. IR LEDs used in reflective mode continuously and precisely determine the product width. The sensor module only needs to be attached on one side of the product. The compact design allows it to be installed even in the tightest mounting spaces. Retrofitting is possible virtually anywhere.
