The production of cables requires compliance with high quality levels and numerous standards. Moreover, cable manufacturers aim to produce economically. Accordingly, manufacturers choose measuring devices that are focused on quality control in their lines. SIKORA has developed efficient and innovative technologies specifically for insulating and jacketing lines that assure quality during the entire production process.
X-RAY 6000/6000 PRO – Intelligent partner at jacketing lines
Measurement of the wall thickness, eccentricity, diameter and ovality of single and multi layer products
For quality control of cables in jacketing lines, the X-RAY 6000 continuously ensures compliance with requested cable specifications regarding wall thickness, eccentricity, diameter and ovality.
In jacketing lines, the X-RAY 6000 is typically installed between two cooling trough sections. In this position, the device measures the outer jacket of the cable. An additional diameter gauge head at the end of the production line, combined with Hot-Cold-Control, considers the shrinkage of the diameter.
X-ray measuring technology for single- and multi-layer products
The X-ray measuring systems, X-RAY 6000, are fascinating in general and in detail. Customers who measure up to three cable layers during production choose the X-RAY 6000 PRO. For cable production lines where only one cable layer is measured, the X-RAY 6000 is available.
LASER Series 2000 – Diameter control at all times
LASER Series 2000 XY-models for classic 2-axis diameter measurement LASER Series 2000 T-models for classic 3-axis diameter measurement LASER Series 2000 S/R-models for the measurement of sector and round cables The LASER Series 2000 includes measuring devices for classic measurement of the cable diameter in 2 or 3 planes. Integrated at the end of CCV-, VCV,- MDCV- and in insulating/ jacketing lines, the gauge heads are characterized by precision, reliability and functionality. The technical base of these gauge heads is a state-of-the-art CCD-line sensor technology combined with laser diodes as light sources and intelligent powerful analysis software. The outstanding feature of the non-contact measuring technology is the extremely high single value precision, which is an important aspect for the calculation of the standard deviation. The short exposure time assures reliable readings at all common line speeds. The LASER Series 2000 is free from moving parts and has a nearly unlimited life time. Even after years of operation the devices measure as accurately as on the day of delivery. The optical measuring principle without any moving parts ensures an availability of 99.8%. Calibration or maintenance procedures are not necessary.
LASER Series 6000 – A milestone in diameter measurement
LASER 6080 XY for high-end diameter measurement amd detection pf lumps and neckdowns The LASER 6080 XY combines a variety of new technological features for a diameter measurement with an impressive precision and reliability to improve productivity of the production line sustainably. 2,500 measurements per second, all with extremely high single value precision allow for an optimum line control and provide reliable statistical data. Integrated display in the gauge head The devices include an integrated LCD display. This provides the operator with diameter values at one glance, directly at the measuring device. Lump detector function The high measuring rate of the diameter devices also permits the detection of lumps and neckdowns. With the two-inone system investment costs are reduced. In addition, there is more space in the line as only one gauge head has to be installed. Interfaces Directly integrated in the gauge head is a universal interface module for all connections such as RS 485, RS 232, Profibus- DP or alternative industrial field busses such as CANopen, Ethernet/IP, DeviceNet, Profinet IO. The interface module as well as all connectors are completely integrated in the gauge head and are perfectly protected against dirt, water or mechanical influences during the production. Wi-Fi interface Gauge head design The opening of the gauge is twice as big as the measuring range to ensure an easy product feed through. A special feature is the swivel type gauge head. It allows the gauge head to be moved up and out of the extrusion line. The measuring head is open at the bottom to prevent dirt and water from falling into the measuring area. The feeding of the connection cables to the interface module is protected, directly in the gauge head stand. Wi-Fi interface The LASER Series 6000 has common interfaces as well as a Wi-Fi interface, which allows for a direct connection to a smart phone or laptop. The Wi-Fi interface is used for diagnosis and quality control. Measuring values, trend and statistical data, but also video signals are transferred. SIKORA App SIKORA offers a free app for displaying measuring values, trends, statistics or video signals, at smartphones. The operator can easily log in via the Wi-Fi interface and receives immediately production data of the particular gauge head from the smartphone. The app allows also the calibration of the gauge head according to ISO 9001. The values of the test probes are read by a QR code and the measured values listed in a log file. For the quality management, a documented test certificate is created, sent and archived.
WIRE-TEMP 6000 – Non-contact temperature measurement
Non-contact measurement of the conductor temperature During the production of cables or wires, the conductor is heated prior to the extrusion process to ensure optimum adhesion of the insulation on the wire. With the WIRE-TEMP 6000, SIKORA presents a system for precise online measurement of the conductor temperature. The WIRE-TEMP 6000 can easily be installed in insulating as well as CV lines after the preheater. Independent of external influences and on a non-contact basis, the WIRE-TEMP 6000 continuously measures the temperature of the conductor prior to entering the extruder, assuring repeatability in the production process. Designed for diameters from 0.3 to 5.0 mm, alternatively from 5.0 to 50 mm, the system is laid out for product temperatures up to 150°C, optionally up to 250°C. The noncontact measurement of the temperature is independent from the cross-section, the material and the surface structure of the conductor. A big advantage over conventional systems is that the temperature measurement is done by means of a thermal image sensor in an infrared camera, which captures the conductor reliably with its wide measuring range.
SPARK 2000 BS – Successful without breakdowns
Alternating-current sparktester (AC) At the extrusion of cables, the insulation has to be inspected by sparktesters (high-voltage sparktesters) and possible insulation defects should be detected and documented at an early stage. For the testing, the dry cable runs through the sturdy bead chain electrode of the sparktester that is installed after the cooling section. Here, the cable insulation is exposed to the selected test voltage and faults in the insulation are detected reliably. Online quality control assures that only faultless cables are delivered. SIKORA offers 8 models of the SPARK 2000 BS, covering the diameter range from 1 to 220 mm. For all systems, the test voltage is continuously adjustable from 1.6 to 35 kV.
LENGTH 6000 – Perfect length
Length measuring systems – new defined The LENGTH 6000 is a reliable non-contact online length measuring device specially designed for the use in jacketing lines. With the LENGTH 6000 cable manufacturers measure the cable length during production and assure that the accurate length is supplied or further processed. The LENGTH 6000 is a reliable non-contact online length measuring device specially designed for the use in jacketing lines. With the LENGTH 6000 cable manufacturers measure the cable length during production and assure that the accurate length is supplied or further processed. The technology of the LENGTH 6000 is reliable for all types of strand-shaped products with reflective and rough surfaces. A very typical application is its use at insulating and jacketing lines. The system recognizes whether the product is moving forward or reverse and measures the length always precisely starting at zero line speed.
