nLine Cable Inspection

Wahtari’s nLine cable inspection solutions can analyse a wide variety of product and quality characteristics in individual inspection (test bench) or Inline during ongoing production. Deviations are signaled and documented.

The systems are available in different versions and can be adapted to a wide range of requirements. The analysis & evaluation is performed on-the-edge, without connection to a cloud, for highest performance, lowest latencies and best data security.

The commissioning does not require any technical knowledge. Product features are simply trained according to the “Teach & Go” principle by using a master sample.

Functionality of the nLine cable inspection solution

The increasing demands on the already high quality standards, e.g. as demanded by the automobile industry, pose problems for error detection by means of conventional measuring and testing technology. In addition, requirements such as 100% control and traceability have to be fulfilled.

nLine 360-Ti3

The nLine 360 Inline cable inspection solution was developed specifically for the extrusion industry and enables the inspection of many different product features in a single compact device. Thereby it replaces the existing measuring and testing technology, which reduces investment and maintenance costs as well as integration efforts. Three high-speed cameras continuously monitor the complete cable surface over the entire cable length.

Easy integration also into existing system concepts

nLine can be integrated into existing system concepts. As a mobile version mounted on a height-adjustable rolling frame or as a compact, stationary version (fixed installation). The uncomplicated commissioning requires little technical know-how. Numerous interfaces and industry standards, such as OPC UA, allow easy integration into existing system concepts while ensuring minimal latencies. Signals, e.g. for the control of signal transmitters, can be directly output via an analog signal. This simplifies the programming of system controls and complex cabling.

Display options / Error output

A clearly visible light signal informs the employee about the current test and operating status.

  • Red, for faults, alarms and any errors

  • Yellow, device is ready but not active

  • Green, device is active and error-free, test is running

  • Dark, device is switched off

Operation and monitoring via touch screen.
