Lump detector for fibre optics

Lump 2000 T technology ensures reliable measuring results. The system defines non-conformities in the product surface – even at production line speeds of up to 3,000m/min. Even the smallest lumps and neckdowns of 0.01mm are detected and analysed. Under difficult conditions, such as extreme vibration, the lump detector ensures reliability readings at the fault detection and as there are no moving parts there is no need for calibration or maintenance. The Lump 2000 T offers diverse interfaces such as RS485, RS232 for PC diagnosis. Optionally, a Profibus-DP-, EtherNet/IP- or DeviceNet-interface for the direct connection to a PC or the display and control devices respectively Remote 2000 and Ecocontrol 600 are available.

Sikora presents a 3-axis lump detector, Lump 2000 T for fibre optic cables. Sikora customers already benefit from the measuring performance of the 2- and 3-axis lump detectors during cable production. With the new special edition of the Lump 2000 T Sikora offers an additional future-oriented technology for the detection of lumps and neckdowns in transparent materials, in particular for the production of fibre optic cables. Gauge heads are available for product diameters from 0.25mm to 10mm as well as 0.5mm to 35mm. The heart of the new lump and neckdown detector is the technically advanced double sensor technology. Using light sources in combination with light sensors the Lump 2000 T detects in three planes the quantity, type, height and depth as well as the length of the fault in the transparent material. Particularly useful is the success of the lump detector for loose tubes. These cable types consist of a hollow transparent plastic tube that includes a number of optical fibres. The cable

is filled with a water-blocking gel in order to prevent the fibres from moving. Conventional lump detecting methods would have difficulties to achieve accurate measuring results in these conditions. The gel inside the tube contains air bubbles, which function like lenses at light incidence and diffract the light.
