Control of thread density / course density / basis weight Famacont PMC with optoelectronic sensor (reflex light) The oscillating lens of the scanner determines precise the thread density in a textile fabric. High power reflex light LEDs illuminate the fabric. Famacont PMC with camera sensor (reflex light) Camera scanner for high-resolution detection of weft thread and course density on running textile webs. The basis weight can be determined by analysing both values. High power reflex light LEDs illuminate the fabric. OPTOLECTRONIC SENSOR / CAMERA SENSOR 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.
