It can measure eccentricity, concentricity, wall thickness, diameter, ovality, and lump/neckdown defects.
English
DALA Metrology provides one-stop wire and cable quality solutions, from diameter to eccentricity measurement, with in-line monitoring of length, lump/neckdown, insulation, and surface defects throughout the production process.
It can measure eccentricity, concentricity, wall thickness, diameter, ovality, and lump/neckdown defects.
More Communication Interfaces
Equipped with RS485, Bluetooth, Wi-Fi, and Industrial Ethernet. Many domestic products support only two communication interfaces.
C3 Touchscreen with More Functions
Supports voltage adjustment, 2-level sensitivity, defect resolution settings, and automatic classification of pinhole and bare-wire defects. It also displays defect count, defect position, line speed, voltage calibration, and user access levels. Many domestic products use only buttons and digital displays, showing mainly voltage and defect count.
Customizable I/O Signals
Supports 8 categories of digital inputs and outputs, configurable for functions such as high-voltage start/stop, defect reset, defect limit alarms, and equipment fault alarms. Output duration and frequency can also be customized.
Bluetooth Remote Control by Mobile Phone
All C3 touchscreen functions can be operated remotely via Bluetooth on a mobile phone.
Adjustable Time Resolution
Time resolution can be adjusted from 1 ms to 2 s. Higher time resolution helps reduce missed defects, while many domestic products do not offer this adjustment.
The minimum detectable surface defect size varies with lens magnification, while the minimum detectable lump/neckdown height depends on the sampling rate.
Typical values are:
For specific applications, please refer to the product selection guide and the Surface Defect Inspection System Brochure, or contact our sales/technical support team for configuration recommendations.
Line speed does not directly reduce eccentricity measurement accuracy. However, it affects the cable length represented by the displayed value through the averaging time, which may influence comparison with cut-sample measurements.
For example, at a line speed of 600 m/min and an averaging time of 2 s, the displayed value represents approximately 20 m of cable. Therefore, when comparing online results with laboratory cut samples, sampling should match the averaging time, while also considering positional variation of the cable at high speed.
No. A spark tester cannot replace withstand voltage or insulation resistance testing.
Spark testing is mainly used for fast in-line screening to detect physical insulation defects such as pinholes or breaks. By contrast, withstand voltage and insulation resistance tests apply voltage for a longer period and are used to evaluate the cable’s overall insulation performance, breakdown resistance, and material quality before final delivery.
The eccentricity measurement system is suitable for round single-core wires and multi-core cables with an approximately round core structure. Typical applications include coaxial cables, LAN cables, and automotive wires.
