InteliSENS® Eccentricity Gauge


The InteliSENS EG Series Non-Contact Eccentricity and Diameter gauge is designed for measuring a range of insulated wires up to 12mm (0.47”) diameter. The EG0112 is ideal for High-Frequency Data Cables where eccentricity is critical for cable performance. The EG0812 can be used for larger wire sizes and is ideal for making sure wall thickness and diameter are kept at an optimum level to maintain quality and reduce material usage.

Automatic centering ensures the cable is centered within the measuring zone. A built-in CDi4 displays 8 Point Wall Thickness, Diameter, and Eccentricity. Focused on connectivity the EG Series features 32bit communication and comes preloaded with Profibus, Profinet, and Ethernet Industrial Protocol for your PLC connection. Modbus, OPC-UA, RS232, RS485, and WiFi are included as standard providing a wide range of digital communications for your Industry 4.0 Solution.

Measuring Principle

The Eccentricity Gauge combines electromagnetic and optical scanning principles. The optical scanning system is used to define the wire insulation outer diameter and the electromagnetic system is used to determine the wire core position, eccentricity and 8 point wall thickness.

Optical measurement is done by sending out light from LEDs which shine on the measuring object thus casting a shadow on the CCD receiver. The image information is then evaluated by integrated signal processors.

The optical measurement and magnetic measurement are performed simultaneously at high rates, minimizing inaccuracies caused by wire vibrations, and both measurements are controlled on the same plane to eliminate the errors due to product twists.
